The 33-year-old actor partied into the early hours of Tuesday morning and was joined by three women in Berlin, including the one who looked like his soon-to-be ex-wife, reported Us magazine.

Once inside Odessa Bar, Kutcher and the Moore look-alike "sat at the open window, talking, flirting, drinking red wine and smoking one cigarette after another," an onlooker said.

Just before 4 am, Kutcher "left the party with three girls in tow, including the Demi Moore look-a-like," the onlooker added.

The foursome piled into the actor's chauffeur-driven car and continued their party at a private apartment. Moore, 49, filed for divorce from Kutcher in November after the actor allegedly cheated on her with another woman on their sixth wedding anniversary.
