Jessica Simpson Cleavage Picture Takes Twitter by Storm [PHOTO]

New mom Jessica Simpson tweeted a shocking picture of herself to her followers over the weekend while taking a stroll with baby Maxwell Drew Johnson in Los Angeles.

The 31 year old star added the caption "Just taking a walk around the block". Known for always making fun of herself, she then added "Street legal???" referring to her ample bosom, which is clearly engorged from breastfeeding.

The other shocker was what appeared to be her cellphone case attached to the inside of the black lowcut top. With a near billion-dollar successful fashion line, you would expected the star to step up the style quotient, not bring it down.

The makeup-less star was taking a stroll for what is likely part of her new exercise routine to quickly shed pounds following the birth of her daughter in May via C-section. And her other motivation?  The reportedly $4 million she will receive from her signed deal with Weight Watchers to lose 50 pounds.

After singer Beyonce flaunted a flawless post-baby body Memorial Weekend a mere six months after delivering baby Blue Ivy with husband Jay-Z in January, Simpson might be feeling the pressure from critics and fans to get back to the Daisy Duke short-wearing svelte shape she is known for and sported in 'The Dukes Of Hazzard" movie.

Simpson admitted she has given up fast food also to help jump start the weight loss process as well. And because she is still engaged to fiancee' Eric Johnson, upcoming wedding nuptials may be another factor.
