He's only 2, but Jayden James Federline already knows how to upstage his famous mama.

"I want to wish everybody out there a Merry Christmas and a Happy New Year," Britney Spears says in a video greeting posted Tuesday on her Web site. "And I want to thank all of my fans for making my album, Circus, No.1."

Standing with her two boys in front of a lavish Christmas tree, the singer then turns to Jayden. "Thank you," she repeats, "as my son burps!"

Before the camera fades to black, Spears is seen kissing him sweetly on the forehead.
