Barrymore appears to be in high spirits since splitting from husband Will Kopelman in April.
The former couple announced that they were divorcing a few weeks before their youngest daughter, Frankie, turned 2.
"Our children are our universe, and we look forward to living the rest of our lives with them as the first priority," the exes said in a statement to People.

Not long after the divorce announcement, Barrymore opened up to ET about how much motherhood has changed her life.
"[Motherhood’s] just made me such a better person," she explained. "I always love and try to live on the high road. I think you feel best when you behave or react or come from the high road place. And my kids have elevated that for me in a way that is indescribable."
