Jessica Simpson pregnant with second baby, report says

After months of criticism, diet and exercise, Jessica Simpson finally managed to shed the weight she gained when she was pregnant with her daughter Maxwell Drew. And now she may gain it all back.

The singer turned fashion designer is rumored to be pregnant again.

According to US Weekly, Simpson, 32, is pregnant with baby No. 2 with finance Eric Johnson.

"It definitely wasn't planned. But yes, Jessica is pregnant again," a source told the magazine of the second pregnancy, which comes just seven months after the “Fashion Star” mentor gave birth.  

Recently, details of Simpson’s weight loss hit the web, revealing the singer dieted on low-fat smoothies and vegetables to lose 60 pounds.

Simpson, who announced the birth of her daughter via Twitter, has yet post anything about the baby rumors.

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.

Simpson's rep did not immediately return FOX 411's request for a comment.
