The former TOWIE star, 23, is fronting the brand’s Sexy For You campaign, posing in a series of sexy underwear shots.
But while Sam’s figure is amazing, she insists she’s not on a mad diet to stay looking good.

Speaking to The Sun said: “I’ve worked hard for this campaign – I train 3-4 times a week in my back garden with a personal trainer. Squats with kettle bells are my favourite but I hate doing lunges, I wobble a lot.
“I have been watching what I eat, I’m not on a crazy mad diet, but I’m not eating any fast food.”

The blonde beauty admits she does treat herself every now and again, but tries not to overindulge.
She continued: “I’ll only indulge one night a week and if I drink, it’s vodka and slimline tonic, no more shots.”
Sam reunited with partner Joey Essex in April, and she says her former co-star loves the pictures from the campaign.

“Joey’s really proud of me for doing this collection, he hasn’t seen the final product yet, but I plan to show him later.
“He’s had a sneaky peek at some of the images and he really likes them.”
But just because she’s the body of Ann Summers now, don’t expect Sam to always be wearing matching undies now.
She added: “I don’t have time to always make sure I’m in matching undies when I’m rushing out of the house – that’s why this new range is great because you can mix and match, and still look sexy.”
