It's not always easy being a supportive spouse.

At the premiere of What's Your Number? in Westwood, Calif. Monday, Anna Faris admitted that her husband of two years, Chris Pratt, isn't exactly the next American Idol.

"He thinks that he's a great singer, but he's really awful! And I don't ever want to tell him!" she laughed. "I'm always like, 'Honey, you should pursue it! Pursue it -- pursue your country album!' He's really terrible. But it always makes me laugh. I can't help it!"

The 34-year-old actress -- who stars opposite Chris Evans, Dave Annable, Joel McHale and Zachary Quinto in the rom-com -- flew solo at the premiere, as Pratt was busy promoting Moneyball in Oakland, Calif.

"It's sad, but I do have my whole family here," Faris told Us. Once her husband, 32, returns home, "We're going to try to escape for a little weekend away or something."
