Big Time Rush poses for pics before the 2012 UNICEF Charity Concert held at the House of Blues in West Hollywood, Calif., on Friday night (January 20).

The guys — Kendall Schmidt, James Maslow, Logan Henderson, and Carlos — hit the stage to perform alongside Selena Gomez.

“Had a great time singing Jason Mraz‘s ‘I Won’t Give Up’ with @selenagomez last night for her charity concert supporting UNICEF! You see it?” Kendall tweeted.

In case you missed it, Big Time Movie will premiere on March 10th!
