Recently, details of Simpson’s weight loss hit the web, revealing the singer dieted on low-fat smoothies and vegetables to lose 50 pounds.

Simpson is making a reported $4 million for her Weight Watchers endorsement role, according to TMZ.

The new pregnancy will not have a huge impact on her deal with Weight Watchers, TMZ reported. A rep for the program told the website she "will not be following the program during the pregnancy while her weight and well-being are monitored by her obstetrician."

After she gives birth she will resume her Weight Watchers diet, according to TMZ.

Simpson and Johnson have been engaged since Nov. 2010. Prior to dating Johnson, Simpson was married to singer Nick Lachey in 2002 and the two divorced in 2005.
