Channing Tatum and Rachel McAdams posed side by side at The Vow premiere in LA last night. Rachel paired dramatic red lips with a strapless Vivienne Westwood dress and nude Christian Louboutin heels while Channing suited up in gray. Channing's wife, Jenna Dewan, hit the carpet in a bright mini, though Rachel's boyfriend Michael Sheen wasn't on hand to celebrate. Channing, Jenna, and Rachel followed the screening with an afterparty at the Hollywood Roosevelt Hotel, where guests snacked on a Ralph Lauren-designed wedding cake. The movie hits theaters on Friday, just in time for Valentine's Day, which we're already gearing up for with a look at 100 hot PDA pictures. Channing and Rachel's characters show plenty of affection in the film, and they chatted about their romantic tendencies when we sat down with the duo for their The Vow press day.
