Jessica Simpson may be on a quest to lose weight, but there may be parts of her new figure she'll be keen to hold on to.

The former singer was showing off her post-baby cleavage as she posted this pic on Twitter over the weekend.

"Just taking a walk around the block... Street legal???" she tweeted.

Jessica gave birth to baby Maxwell with fiancé, former NFL star Eric Johnson, at the beginning of last month.

The star wants to lose 50 pounds in five months and has been hitting the gym hard to shift the baby weight.

She has had five workout sessions in two weeks, and according to US magazine InStyle, she is feeling the pressure of her goal.

A source told them: "She’s so emotional. She doesn’t want to leave her baby. Sometimes she just starts crying. It’s hard for her."
