Model separates from husband after raunchy shoot with Justin Bieber

The supermodel who featured with Justin Bieber in the raunchy Calvin Klein ad in January is no more married!

Lara Stone reportedly left her husband, David Walliams on Tuesday night [March 3], taking along her 22-month-old son, Alfred and their dog, Bert.

Despite the fact that she hasn't explained the reason behind her move, many believe it has everything [or not] to do with the semi nude photos she made with C.K.

Another set of pictures of Lara were also released by i-D magazine, after the CK set, with the supermodel fully naked with 'Fifty Shades Of Grey' actor, Jamie Dornan.

However, sources close to the couple tell MailOnline that Walliams, 43, is "devastated" that his wife left their North London home and is hoping against hope for a reconciliation.

Another source claims Lara has had enough of her husband (who is also a judge on X Factor USA) and there's no possibility of a reconciliation.

An associate of Walliams, who has often spoken of his struggles with depression and suicidal impulses, told me: "There have been big problems with the marriage for longer than you might think. Certainly, I was aware of the schism around six weeks ago. He didn’t broadcast it, but his friends were made aware that they were in a difficult place, that the marriage was in trouble. He is very sad about it but has been putting on a professional front."
