Jessie J is opening her Christmas presents well in advance of the holiday this year in her new promo video for Vitamin Water.

The pop star's super cute clip shows off her vibrant personality, offering quick cuts of the singer making jokes and acting giddy. After all, she's trying to figure out what's hiding underneath all that wrapping paper!

The set of the video incorporates a bevy of brightly-wrapped gifts, and looks as if it was inspired by the British songbird's 'Price Tag' video. Of course, the rainbow of colors also reflects the aesthetic of the beverage.

So, what's all the fuss about? Jessie has been tapped as the Olympic Ambassador for the company, and the promo is encouraging viewers to "guess Jessie's pressie" on Vitamin Water's Facebook page. By doing so, fans can enter to win tickets to the 2012 Olympic games in London. Not a bad deal.

"The London 2012 Games is a once in a lifetime event and I am so excited to have the chance to be a part of it," Jessie said in a press release. "It is a chance to show Britain at its best with music and sport and creativity combined. Good times."
