"You just get better, calmer, smarter, wiser, and also with the life span now, 40 is the new 30, 50 is the new 40," Barrymore, 41, said as she hosted the Pokémon Afternoon Soiree at on Saturday in West Hollywood. "You have to really work hard at like being someone who has inner piece and real educated about your own life decisions. And that just takes time."
Along with getting calmer, smarter and wiser, Barrymore also loves the way her style has evolved in her fourth decade.
"I'm not a skin-tight girl. I don't even want knee cleavage," joked Barrymore. "Quote me on it, I don't like knee cleavage. I don't like breast cleavage. I don't want any cleavage. Like to me, forearm and collarbone are so sexy, and back. Four inches of ankle goes a long way."
The mom of two young daughters, Olive, 3, and Frankie, 22 months – "They are the greatest things in the world," she said – also took time to address Patricia Arquette's equal pay movement.
"I signed her petition," she says. "Of course, immediately. Reese Witherspoon sent a mass email. I got it, signed it within three seconds and sent Reese and email back saying, 'Signed, done! Thank you for the awareness. I hope this works. Let me know if you need anything else.' "
