Witherspoon shares Deacon and Ava with ex-husband Ryan Phillippe, 46, whom she married in 1999 after they starred together that year in Cruel Intentions. They announced their separation in 2006 before finalizing their divorce in 2008.

During an appearance on The Drew Barrymore Show in September, Witherspoon opened up about becoming a mother when her career first took off. "To be completely candid, I was terrified too," the Oscar winner said of being a young parent. "I got pregnant when I was 22 years old and I didn't know how to balance work and motherhood, you just do it."

"I didn't know if I was going to have steady work, too," Witherspoon continued. "I made movies but I hadn't established myself as someone who could demand that it shoot close to my kids' school."

"I guess that's how it goes with 3 kids, Big LOVE, lots of laughing, non- stop travel, so many dogs, and fun adventures… figuring out this crazy world together. Here's to many more days in the sun! I ❤️ you, JT," she added.
