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

"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!"
