Shes got a 9-month-old daughter and is currently pregnant with her second child.

But it'll take more than that to stop Jessica Simpson from carrying on with work as per usual and dressing to impress as she does so.

The 32-year-old shunned traditional maternity wear in favour of a sexy leopard print dress as she showcased her bump while filming a commercial on Monday.

Bumping: Jessica Simpson was seen filming an advert on Monday in LA showing off her bump

Falling to the middle of her thighs Jessicas tight fitting dress meant her baby bump took centre stage.

Having kept her bump under wraps for much of her pregnancy so far, it was an opportunity to see how much her stomach has grown in recent weeks.

She teamed her wild dress with a simple black cardigan and a pair of black heels, which gave the petite star a bit of extra height.

Her legs meanwhile looked particularly toned and showed no sign of any extra pregnancy weight.

Jessicas long blonde locks ! had been styled into loose curls and her glamorous look was completed with dark eye make-up and a dash of pink lipstick.

Joining the clothing line owner on set was fianc Eric Johnson and their daughter Maxwell.

The father and daughter stood at the side-lines watching Jessica work her magic on set, giving little Maxwell a chance to see what mummy does when shes not fulfilling her mummy duties.

Eric looked every inch a cool dad wearing a simple all-black ensemble with a black hoody.

Shielding his eyes he wore a pair of shades and a black baseball cap, while he sported his usual amount of facial hair.

However it was little Maxwell who stole the show from the side-lines wearing a pretty pair of pink trousers with floral pattern and a grey T-shirt , while her hair was clipped back with a cute pink bow.

It is unclear exactly what the commercial was for that Jessica was filming, however she is a well-known ambassador for Weight Watchers.

In between juggling filming with running her hugely successful fashion brand, its thought Jessica and Eric have already come up with a name for their child.

A source told Us Weekly magazine: 'She's told people she's going to name the baby Ace.'

The moniker made famous by Jim Carrey's character in the 1994 movie Ace Ventura: Pet Detective, tends to be a boy's name and means 'one' or 'expert.'
