Amanda Seyfried & Dominic Cooper: Golden Couple!

On-and-off-screen couple Amanda Seyfried and Dominic Cooper (in Burberry) party together at the NBC, Universal Pictures and Focus Features’ official after party for the 2009 Golden Globe Awards at the Beverly Hilton Hotel on Sunday (January 11).

The Mamma Mia! stars went on a shopping date together at Barneys New York in Beverly Hills last week.

“The fact that I felt something in my heart for [Dominic] made me feel that something was definitely wrong,” Seyfried told the Daily Mail. “I sat and thought about it for weeks… We just spent time together and it was something nice.”
