Lara looks amazing in this series of sexy 1990s-inspired photos, and yes, she's well and truly back in her skinny jeans after giving birth to her son Alfred in May 2013.
The Dutch-born model and Mrs David Walliams is more than happy to flaunt her fabulous figure (she's been on the James Duigan's Clean & Lean diet) in the brand's signature underwear.
"My relationship with Calvin Klein has spanned many years and it's an honour to be a part of this iconic brand's legacy and to be featured in such timeless creative," said Stone.
"The campaigns are always so beautifully and artistically presented – and are always fun to shoot. Matt and I have a great working relationship and it's always a fantastic atmosphere on set with Mert and Marcus."

In an interview with Net-A-Porter's digital magazine The Edit this month, Lara revealed that she knows exactly what it feels like to have body hang-ups but that after working alongside Bodyism founder James Duigan she's in a whole new place.
"It's a whole change in lifestyle. I feel a lot more balanced. My energy is much steadier. I feel stronger and more confident."
