There's no event quite like the Olympics for bringing a country together, and so far the London 2012 games have been a great excuse for patriotism on both sides of the pond.

With America currently beating the UK in total medals won thus far this year, there's been plenty to cheer about -- and just about everyone, from the cast of "The Vampire Diaries" right through to the President of the United States, has been vocal in their support of Team USA.

Whether it's Justin Bieber recording a video for swimmer Missy Franklin or Ian Somerhalder declaring his appreciation for Gabby Douglas, we've rounded up some of the most memorable messages of support from the famous fans of our current Olympic heroes. (We're sure there'll be even more to come in the next few days.)
