Jessica Simpson Baby Bump Revealed

Jessica Simpson is no longer hiding the fact that she is expecting her second child and has revealed her baby bump for the first time on Sunday.

The singer posted a new picture to Twitter of her reflection in a mirror while wearing a bikini.

"Bumpin' and proud," Simpson wrote as the caption.

A makeup free Simpson appeared already heavily pregnant in the image despite having welcomed her first child just seven months ago.

It was long rumored that the "Sweet Kisses" singer and her fiancé Eric Johnson were expecting baby number two, but the pair finally confirmed the news on Christmas Day.

"Merry Christmas from my family to yours," the 32-year-old posted to Twitter along with a picture of daughter Drew sitting before the words "Big Sis" written in sand.

This is not the first time Simpson has taken to Twitter with baby news.

Last year, the "Sweet Kisses" singer confirmed her first pregnancy on Halloween cryptically tweeting about her "Mummy" costume.

"It's true," she wrote on Twitter at the time. "I am going to be a mummy!"

As with her first pregnancy, it is believed her second pregnancy was also unexpected.

"It definitely wasn't planned," Simpson told Us Weekly soon after welcoming Maxwell.

Although Simpson has clarified the baby rumors, gossip continues to swirl that she and Johnson are planning to wed at the end of the year. Simpson and Johnson have been together since 2010.

"For the holidays, Jessica and Eric are going to Hawaii and they've invited a lot of their close friends and family," an insider revealed to RadarOnline. "No one quite knows that is being planned, but family members are speculating that they could be planning a surprise wedding."

Meanwhile, the singer-turned-fashion-mogul and her NFL star fiancé welcomed their daughter Maxwell on May 1. Following the child's arrival, Simpson signed a lucrative deal with Weight Watchers and worked hard to shed over 60 pounds in recent weeks.
