The blonde star showed off her ample cleavage in the new designer bra.

Lara showed off her bust at fa film screening with husband David Walliams earlier this week.

On Tuesday night she proved she didn't need much help in the cleavage department, but that hasn't stopped Lara Stone from modelling a new push up bra.

The pretty Dutch model has been revealed as the face of Calvin Klein's new push up bra in a sexy new video, and what better way to promote it than with the hit Salt-n-Pepa song that goes by the same name.

In the 30 second advert, Lara can be seen dancing around in the black underwear that highlights her ample cleavage.

'Push it, push it good,' the 28-year-old says as she looks into the camera, while the Eighties tune plays on.

Calvin Klein are promoting the garment as their 'new soft wire push up' and it seems that Lara was the perfect female to model it.

As the advert comes to an end, she gazes into the camera one last time and says again: 'Push it good.'

Perhaps Lara was wearing the bra when she accompanied her husband, David Walliams, to a screening of the James Bond film, The Spy Who Loved Me, in London on Tuesday evening.

Lara looked stunning in a black zip up mini dress that certainly showed off her chest the best it could.

Her comedian husband looked rather smart in a black tux and kept a firm arm around his pretty wife.
