Ashton Kutcher Goes Wild in Berlin!

Ashton Kutcher already stabbed Demi Moore in the back by cheating on her on their anniversary. Now, just weeks after she filed for divorce, he's twisting the knife by flirting his way through Europe — and spending the night with a Demi look-alike!

Ashton was spotted drinking and smoking up a storm at a private loft party in Berlin on Dec. 19 — after drinks at Grill Royal, the Neue Odessa bat and Soho House. "He was definitely in a flirty mood," an eyewitness tells Star. "He was surrounded by women all night long." And he was loving it. 

Approached by a reporter for German Magazine In at the bash, Ashton, 33, proclaimed that it was "great!" to be back on the singles scene. "I'm single, why shouldn't I get to meet and get to know women?" And if they're cute, he said, "even better!"

At that, a source says, he took a gulp of wine and turned his attention to a beautiful brunette with waist-long hair standing nearby. After chatting, smoking, and drinking together on a windowsill, the source reveals, Ashton asked her and her two friends to leave with him: a blonde in knee socks and a trench coat and a brunette wearing a sheer top and a fur coat. At 3:47 a.m., the sexy trio was spotted getting into his limo.
