Petra Nemcova has stripped down to bare essentials for a saucy new lingerie ad campaign.

The former girlfriend of singer James Blunt has replaced English glamour model and actress, Gemma Atkinson as the new face and body of underwear chain La Senza.

"Lingerie modelling makes you feel so sexy and good about yourself. I really enjoyed the shoot, there was a fantastic team - we had tons of fun. Some are sexy, some girly, some comfy and some a bit more risque - but they all make you feel great,” the Daily Mail quoted Nemcova, as saying.

"My favourite garment was the black push-up bra - it had such great shaping but still has very thin straps,” she added.

After being spotted by a talent scout in Czechoslovakia at 16, the 28-year-old has modelled for fashion bible Vogue and is a popular Sports Illustrated cover girl.
