James Marsden lit up with a nervous smile on Wednesday when Ryan Seacrest 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 on Today. Watch James's performance above, and then get caught up on the latest viral videos.
