Justin Bieber will serenade President Barack Obama and his family this Christmas (11).

The Baby hitmaker first met the leader, his wife Michelle and their two daughters during a White House event last Easter (10) and now they're set to spend another holiday together when Bieber jets to Washington, D.C. to sing songs from his new Christmas album for the first family and a number of prestigious government officials.

Bieber tells radio station KISS FM, "His kids really like me. I'm doing Christmas in Washington and performing for him and the whole Senate."
