Jessie J Flaunts Her Hair One Final Time Before She Shaves Her Head For Charity!

Aww! It warms our heart when celebz go above and beyond the call of duty!

Tomorrow is Red Nose Day, an unofficial holiday where celebz do wacky stuff to raise money for a variety of noble causes!

For Rick Gervais , RND means revisiting The Office with HIGHlarious results!

For Jessie J ? Well, her task is slightly less funny!

The Nobody's Perfect singer vowed to SHAVE HER HEAD in an effort to earn cash for charities!

That's one heck of a commitment! We admire her pluck!

Get one last glimpse of her posing with all of her wonderful hair (above) while you still can, because tomorrow she's going under the knife!!

Congratz on being an outstanding community servant, JJ, we hope you raise barrels upon barrels of buckaroonies!
