Amanda Seyfried graces the cover of January's In Style magazine, and in addition to talking about her roles in 'Les Miserables' and the biopic 'Lovelace,' she also dished about Channing Tatum's sex life.

Because ... when in Rome.

The pair co-starred in that flop of a movie 'Dear John' together, so In Style asked Seyfried for some insight about the newly-crowned Sexiest Man Alive.

"Channing [Tatum] was amazing. He's a superstar," she said of the actor, who had quite a year thanks to hit movies like '21 Jump Street' and 'Magic Mike.'

"Everybody wants to have sex with him," she continued. "And the only person he wants to have sex with is his wife, Jenna [Dewan-Tatum]. He's the most loyal husband."

Thanks for that pin in our balloon, Amanda. Maybe for your next trick you should find some little kids and tell them Santa isn't real.
