It was a British pop invasion at the Q102′s Jingle Ball concert in Philadelphia.
UK acts The Wanted, Cher Lloyd, Ed Sheeran and Olly Murs all took to the stage to perform at the US concert.
Performing at the Wells Fargo Center, Justin Bieber joined the British line-up to spread some festive cheer!
It’s thought Lindsay Lohan also made her first public appearance since her arrest in New York.
It seems she really is a fan of The Wanted!
