Here's Ashlee Simpson's post-Bronx bikini body making it's acting debut on US TV drama, Melrose Place.

Ten months after becoming a first time mum, the singer/actress is shown stripping down to a skimpy red patterned two-piece and diving into a pool in a new remake of the hit nineties show.

In the noughties revamp, the 24-year-old plays small-town girl Violet Foster who relocates to Los Angeles in a search for her birth mother.

Ashlee gave birth to son Bronx Mowgli by husband, Fall Out Boy rocker Pete Wentz, in November 2008.
