kellycalvinklein_impressed.jpgThe pants master himself, Calvin Klein, is reportedly so impressed by Kelly Brook's underwear range, that he felt the need to tell her so when he bumped into her recently in London.

Klein took his chance at Claridge's Hotel on Friday to tell Brook how much he loved her lingerie designs for New Look.

"She thought it was all a bit strange that he even recognised her," a source told The London Paper.

"He also raved about the range of underwear she created."

But that wasn't all. The famed designer also expressed his delight over Kelly's patch-up with boyfriend Billy Zane.

"He said how pleased he was that she and Zane are back together," added the source.

Hmm... I wonder if CK would consider replacing Eva Mendes for Kelly Brook on his next underwear campaign?
