Jessie J wants to gain weight

MOST New Year’s resolutions include dieting.

Not for Jessie J.

The British singer says her goal for 2012 is to gain more weight.

Jessie J says she’s “been working hard this year” and that “it’s important to know when you need to gain weight, or when you need to lose weight and be healthy.”

The 23-year-old is known for her slim figure and skin tight outfits.

The singer also plans to shave her head for charity.
