Talk about a match made in music heaven! British boy band One Direction joined US pop sensation Big Time Rush on Friday in Chicago and Celebuzz has got photos of all the on and offstage fun.

1D members Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson started off their day by heading down to 103.5 KISS FM for a special meet and greet and in-studio performance of “What Makes You Beautiful.” Next, the boys then headed over to the Rosemont Theater for a soundcheck where they were greeted by hundreds of awaiting fans. 

Has 1D mania hit the States? We certainly think so!
