Britney Spears' Christmas Message Interrupted By Son's Burp! VIDEO

Britney Spears' youngest son Jayden James adds his own contribution to his famous mother's Christmas message - a big burp!

In a new video, the popstar gets into the festive spirit to thank fans for their support.

With a lavish Christmas tree in the background, Britney holds Jayden in her arms while clutching on to Sean Preston's hand.

The star begins her Christmas message but is interupted mid-speech by her two-year-old son burping.

In the clip, Britney says: "I want to wish everybody out there a Merry Christmas and a Happy New Year. And I want to thank all of my fans for making my album, Circus, number one."

Britney turns to Jayden after he lets out a belch.

"Thank you," she repeats, "as my son burps!"

Britney then kisses her youngest on the forehead.
