James Marsden lit up with a nervous smile on Wednesday when Ryan Seacrest [1] talked him into singing Garth Brooks's classic "Friends in Low Places" on his radio show. Not even the actor's dimples could prepare us for the swoon-worthy performance that followed. Joined by Lady Antebellum, James gave it his all, crooning with a country twang while Michelle Monaghan, his costar in The Best of Me, captured the moment with her phone. Singing live is nothing new for the actor, though — while promoting Hairspray back in 2008, James sang with his costars [2] on Today. Watch James's performance above, and then get caught up on the latest viral videos [3].
