Jessica Simpson
is one hot mama! 

The blonde beauty looked every bit a celebrity as she was spotted at LAX in Los Angeles on Tuesday.

Sporting black from head-to-toe, the singer showed off her slim figure in tight leather pants, a black tank top and a black fur jacket. Simpson finished off her chic airport style with round sunglasses and a giant black tote.

The 33-year-old has been raving about her diet plan with Weight Watchers, and recently said that her upcoming wedding has given her a real incentive to stay slim.

"The new year will definitely bring on the wedding bells, which is exciting…I think it's about time,"she told People.

"Knowing that I have the wedding coming up is an incentive to stay on Weight Watchers, count my points and stay in the gym," Simpson added. "I mean, when you see my dress, you’ll know!"
