If Drew Barrymore could give some advice to her younger self, it would be this: Everything is going to be OK. “I’m so happy now, and I have such a good thing in my life with my kids and everything,” the Santa Clarita Diet actress told Us Weekly and other reporters on Sunday, April 24, at the Safe Kids Day in Culver City, California.

The 41-year-old, who announced her split from her husband of nearly four years, Will Kopelman, on April 1, has no time to wallow. Barrymore’s daughters, Olive, 3, and Frankie, 2, are keeping her busy. “Yesterday, Olive got into my lipstick and it was a real scene,” the Flower Beauty founder told Us. “Let’s just say the whole face got covered, then the hands on the walls, everywhere … I was like, how did this happen in three minutes? It took over an hour to get it off of her. It was nuts.” Making matters worse: It happened right before Frankie’s birthday party.

Happy birthday to my angel Frankie. Happy earth day birthday! And happy earth day to all!!!!!!! #2yearsold #naturegirl

But despite the hitch, the bash was a success. “It was so sweet and delicious,” Barrymore raved. “We had a Minnie Mouse cake, and it was like the best thing ever.”

The former child star recently recounted a conversation with her best friend and film business partner of 21 years, Nancy Juvonen, who’s married to late-night host Jimmy Fallon. “I’d go to her about relationship advice and I’d be like, ‘I just don’t understand why this keeps happening!’’ … I mean, this is exactly what happened last night. It’s just like every single time,” she revealed during a Q&A with Good Housekeeping on April 19. “She’s like, ‘I did notice that there’s a common denominator problem in all your relationships, and I’d like to identify it right now … She’s like, ‘It’s you.’”

Barrymore has been divorced twice before. At 19, she had a two-month marriage to bar owner Jeremy Thomas, and she was wed to comedian Tom Green for five months in 2001.
