Jessica Simpson REALLY gets her body confidence back as she nearly pops out of low-cut frock on date night with Eric

Risky move: Jessica Simpson nearly popped out of her low-cut dress last week on a triple date with sister Ashlee Simpson and BFF Cacee Cobb and their beaus in LA

Feeling confident: The fashion mogul looked like she was in danger of popping out of the strapless black mini-dress, which barely managed to contain her bust

The mother-of-two clung tightly to her 34-year-old partner, who looked suave in all-black.

He gallantly ferried her out of the restaurant, not letting her go as they made their way to their car.

The pair recently returned from a whirlwind romantic jaunt on the Island of Capri, where they were scouting potential wedding locations.

The couple were joined by Jessica's sister Ashlee and her new boyfriend Evan, who is Diana Ross' son.

Ashlee was elegant in high-waisted black trousers and a sheer blouse that revealed her black bra underneath.

The 29-year-old wore a furry coat, red heels and a jaunty hat, and added a pop of colour with crimson lips.

Black must have been the order of the night, as Evan, 25, wore the colour from head-to-toe as he held his girlfriend's hand.

Cacee, meanwhile, showed off her sensational post-pregnancy figure in an elegant black frock.

The 35-year-old, who gave birth to son Rocco in August, left little to the imagination with the plunging neckline.

She wore her blonde hair in curls over her shoulders and kept her makeup natural.

Her husband Donald was casual in a blue V-neck sweater, jeans and trainers.

Jessica gave birth to son Ace in planned C-Section on June 30, and since then she's been working to slim down again.

'When I had Maxwell I gained a lot of weight. More than I thought I would,' the Weight Watchers spokeswomantold Tumblr's MomFeeds blog.

'And when it came time to try to take it off, it felt overwhelming.

Jessica, who is being paid $4 million to be the program's spokesperson, added: 'Stepping on the scale and seeing that number was really scary.

'With a toddler on the run and an infant to look after, I knew I needed a plan that's simple and fits into my life along with the support that's so important to my success. I know Weight Watchers works so I got on the plan again.'

And she says the system has helped her to feel more confident than she has in years.

'I'm a lot more confident this time around. With Maxwell, I didn't think about the weight I was gaining, and the first time I stepped on a scale and looked at the number - I mean, that wasn't a number I had ever even considered - I was faced with a pretty serious truth.'

She added: 'But since I had already done Weight Watchers, I didn't put on as much weight with Ace and I just know a lot more now.'
