El Moussa and Anstead have both been married to the Christina on the Coast star. El Moussa, 39, is her first husband and current Flip or Flop costar, while Anstead, 42, is her most recent ex from whom she announced her split in September after less than two years of marriage.

"I love it! I love it!" El Moussa told PEOPLE of Anstead's new romance with the two-time Academy Award winner, 52, on Thursday at the JBL True Summer Campaign kick-off celebrating a return to Live Music and a donation to the National Independent Venue Association's #SaveOurStages initiative.

El Moussa attended the event with his fiancee, Selling Sunset realtor Heather Rae Young, 33, and both stars opened up about the burgeoning relationship, saying that they're incredibly happy for him.

"I know, like rock on!" Young added.

"Good for him. Ant's a great kid, [Zellweger] seems like a lot of fun," Tarek continued. "I like them. I like the setup."

Young then spoke about photos of Zellweger spending time with Anstead and Haack's one-year-old son, saying, "I've already seen pictures of her with Hudson, so, you know, cute!"

A source told PEOPLE that Zellweger and Anstead have quickly hit it off. "Sometimes two people just meet and click, and the timing is right," the insider said. "Renée is creative...and often goes for guys who think out of the box. She's smart, thoughtful, and always looking to expand horizons and nurture those around her."

"Both of them are private and dislike public scrutiny, so they have that in common," the source added. "He's a creative guy with lots of interests, and she likes to write and produce, so they have things to talk about when together."
