After splitting from her high school sweetheart Robin Thicke, Paula Patton says she realized she had some growing up to do.

The 39-year-old actress shared on The Meredith Vieira Show that she feels that her nine-year marriage and 21-year relationship with the "Blurred Lines" singer has held back a bit. "I went from my parent's house to moving in with Robin, and now I'm becoming an adult," she confessed on Tuesday. "I'm really, like a real woman now."

The couple's split seems amicable. In addition to Thicke's album, Paula -- dedicated to his estranged wife -- Patton also had nice things to say about her ex to Vanity Fair. "We've known each other since we were teenagers," she said in the June 2014 issue. "All I can tell you is there's a deep love there -- always was, and always will be."
