Reese Witherspoon has lost her mind, and her baby boy is to blame. That's what the Oscar-winning actress, 37, tells British magazine Red in a revealing new interview -- conducted before the Mud star's surprising disorderly conduct arrest in Atlanta on April 19.
"Ever since I had the baby, I can't remember anything. Serious, this child stole my brain," says Witherspoon, who welcomed son Tennessee (her third child) last October with husband Jim Toth. "I'm losing friendships over forgetting to get back to people," she continues. "But you can't keep up with everything. I've got a 13-year-old [Ava Phillippe], a nine-year-old [Deacon Phillippe] and a baby."
Keeping track of her three kids, she says, is "like CNN ticker tape running through my mind at all times . . .'Where is Ava? She's okay. Good. Where is Deacon? He's okay. Good. Where is Tennessee? Is he okay? Yes. Great. Back to Ava…' It doesn't stop."
Witherspoon also speaks at length with the mag about her growing acumen as a businesswoman ("I feel like I know what I'm doing now") and reveals that her Best Actress Academy Award (for 2005's Walk the Line) has been moved from her bedroom to a more public lounge in one of her homes -- serving as a motivator and mood lifter. "Because Lord knows every day is not a success, every year is not a success," she offers. "You have to celebrate the good."
Although the star's girl-next-door persona took a slight hit with last week's arrest, Witherspoon, at the time, said that fans generally greet her with smiles and hugs. "People definitely hug me a lot, and hand me their babies. But it's better than people throwing stuff at me, right?" she jokes. "I'm always met with smiles."
In addition, the natural blonde opens up to Red about her friendships with fellow A-list women Drew Barrymore and Cameron Diaz. "They're just as charismatic and fun as you would imagine. It's nice to hang with Drew because we both just had babies and we can support each other," she says of Barrymore, 37, who welcomed daughter Olive last fall. "And Cameron is such a funny, bright gal. She's an incredibly sharp business-minded woman, but she disguises that side of herself. It's her secret alter ego."
"I don't know what I would have done so many times in my life if I hadn't had my girlfriends," admits the star, who leaned on Diaz, Chelsea Handler and other friends in NYC shortly after her arrest. "They have literally gotten me up out of bed, taken my clothes off, put me in the shower, dressed me, said, 'Hey, you can do this,' put my high heels on and pushed me out the door!"
