October 2017: Christina Hall and Ant Anstead started dating.

In December 2016, Hall, 38, and Tarek El Moussa, 40, her then-husband and "Flip or Flop" co-star, announced they were separating. Hall and El Moussa had two children together during their marriage, Taylor, 11, and Brayden, 6.

Eight months later, a mutual friend introduced Hall to "Celebrity IOU: Joyride" star Ant Anstead, as House Beautiful reported. Anstead, 43, had two children from a previous marriage, just like Hall.

They initially kept their relationship private, and they only revealed they started dating in October on their one-year anniversary.

January 1, 2018: Hall and Anstead announced they were a couple.

After dating privately for three months, Hall and Anstead shared they were dating through an Instagram post.

Hall posted a now-deleted photo of the pair biking together, congratulating him on the new season of "Wheelers and Dealers" in the caption, as People reported.

Hall and El Moussa's divorce was finalized later the same month.

December 22, 2018: Hall and Anstead tied the knot.

Hall and Anstead got married at their home in Newport Beach, California.

They didn't make their engagement public before saying "I do," but Anstead said he and Hall were "celebrating something special" in the caption of a photo he posted of Hall on December 17, according to People.

"We pulled off the perfect surprise wedding," Hall told People of the nuptials at the time.

March 22, 2019: The couple announced they were expecting a baby.

Hall and Anstead shared that they were pregnant in a now-deleted Instagram post.

"The kids are all so excited to meet their new sibling," Hall captioned the post.

April 8, 2019: Tarek El Moussa accidentally announced the gender of Hall's baby.

Hall's ex accidentally shared that Hall and Anstead were having a son on TMZ Live.

A representative for Hall and Anstead then confirmed the news to People in a statement.

"While Christina and Ant wished they could have shared the news themselves, they are very excited to welcome a baby boy in the fall," they said.

September 6, 2019: Hall gave birth to their son Hudson.

Hall took to Instagram in another now-deleted post to share that she had given birth to her third child.

"Ant and I are so excited to welcome Hudson London Anstead into the world. Our hearts are SO full of love and joy," she captioned the post at the time.

Hall also documented Taylor and Brayden meeting their brother for the first time in her docuseries, "Christina on the Coast."

September 2020: Hall and Anstead announced they were separating.

The couple announced they were separating just a year after Hudson was born. Hall shared the news in a now-deleted Instagram post, according to People.

"Ant and I have made the difficult decision to separate. We are grateful for each other and as always, our children will remain our priority," her statement said. "We appreciate your support and ask for privacy for us and our family as we navigate the future."

Anstead also announced the separation on his Instagram. His caption seemed to indicate Hall had initiated the separation.

"Anyone who really knows me knows that I don't like to share private matters publicly. I have remained silent while holding on to hope," he captioned a selfie of the pair. "I never gave up on us. I pray Christina's decision brings her happiness."

January 2021: Anstead told People he and Hall were co-parenting amicably.

Anstead told People that he and Hall weren't struggling to share custody of Hudson at the time.

"There's never been a scenario where I've asked for him and not had him and vice versa," he told People.

June 2021: Hall and Anstead's divorce was finalized.

A representative for Hall confirmed the marriage was officially over to USA Today.

Hall had already started dating real-estate agent Josh Hall by the time the divorce was finalized, and Anstead started dating Renée Zellweger in June 2021, according to Vanity Fair.

Hall went on to marry Josh in April 2022.

April 28, 2022: Anstead filed an emergency motion for full custody of Hudson.

In his court filing, Anstead said he was Hudson's "primary parent," saying Hall only spends an average of "9 full days each month" with their son each month, according to People.

TMZ also reported that Anstead said in the court documents that Hall had put Hudson in "dangerous" situations, including a sunburn so severe it made him cry.

On another occasion, Anstead said Hall returned Hudson to him without telling him her family had COVID. "At the time my partner was filming her new project and her covid diagnosis placed the whole production on pause," he said in the filing according to TMZ, referring to Zellweger.

The filing went on to say that Hall uses her time with Hudson to post him on social media, sometimes for sponsored content, as People reported. Anstead requested a judge block Hall from posting Hudson in any "commercial endeavor" until they reach a new custody agreement, according to the outlet.

People reported that Anstead was requesting a "regular" custody schedule that would give Hall visitation rights on "alternating weekends, Friday at 4:00 p.m. until Sunday at 6:00 p.m. commencing May 6, 2022, in California only, and except for vacations."

"This will allow Christina's time to be stepped-up over the next several months to match the schedule she has with her other children," the filing said, according to People.

Anstead declined to comment on the matter when contacted by Insider.

April 28, 2022: Hall spoke out against Anstead's motion in a statement to Insider.

"What Ant is doing deeply saddens me," Hall said. "If this was really about Hudson, as he says, this should have been handled privately with a private judge or mediation, as myself and my attorney have suggested."

"I have had my share of ups and downs, but I am a good mom and I love my children with all my heart and I will always protect them," she went on to say.

She also posted a Jill Blakeway quote on Instagram on Thursday that seemed pointed at Anstead.

April 28, 2022: A judge denied Anstead's custody request.

A judge denied Anstead's ex parte custody application on Thursday both because he did not give Hall enough notice and he did not provide sufficient evidence that Hudson was in danger, according to People.

The judge's ruling states there will be a hearing on June 28 to determine whether or not Anstead's custody request should be granted, as People reported.

Representatives for Anstead did not immediately respond to Insider's request for comment. Hall declined to comment on the judge's decision.

April 29, 2022: Hall filed a response to Anstead's emergency motion.

In the paperwork, Hall said she was "shocked to see the false allegations against me" as well as Anstead's "belief that he has been failing to protect our son by sharing custodial time with me," according to People.

She went on to deny multiple allegations Anstead made against her, saying he was "misleading" the court about their custody arrangement, as People reported.

"Mr. Anstead has now taken the position that he is the defacto primary parent of our son, which is not accurate," she said, according to People. "Anstead does not count any day wherein we exchange our son as a custodial day for me. He also counts days where I made an accommodation or gave a right of first refusal to him as his day."

"That is why there is a huge discrepancy in his mind from our accurate schedule. His attempt to mislead the court is transparent when presented with the true facts," Hall went on to say, according to People. "I do not count my accommodations as decreasing my custodial time, but as me being a supportive coparent."

Representatives for Anstead and Hall did not immediately respond to Insider's request for comment.

April 29, 2022: Hall's husband said he would protect her kids from "unnecessary trauma" in an Instagram post.

Josh posted a photo of himself, Hall, and her three children on Friday, saying he will "always protect her."

"Never did I think taking on 3 kids from 2 other males would be easy. What I was sure of, the woman connected to them was worth it all," Josh captioned the post. "I am not these kids biological father, they have those. What I will be is the best example of a quality human being, always show them how to treat their mother with respect and support them in any way I can during their development."

"Christina and I will always remain unfazed by any outside noise and save the kids from any unnecessary trauma," he went on to say.

"I will always protect her, keep her safe and no one will hurt her with me in the picture," he said. "She doesn't bother anyone, she deserves the same in return. I will ensure that's the case."
