Simpson, 30, is also trying out a vegan diet because her fiance Eric is a longtime vegan. The couple celebrated Thanksgiving this year by cooking a tofurkey, a vegetarian "turkey" made of tofu.

Jessica, who worked out and dieted nonstop to play Daisy Duke in the 2005 flop The Dukes of Hazzard,
says one of the lowest points in her life was being ridiculed by tabloids in January 2009 after being photographed looking heavier than usual in unflattering “mom jeans.""I went through a really hard time a couple years back with people just harping on the pressure of how to look perfect -- obviously using me and my weight," she recalls. "It was a tabloid frenzy."
Simpson says she's happier now at 30 than ever before, and is looking forward to her future with Johnson. Jessica was previously married to singer Nick Lachey before the two divorced in 2005.
