Guess Kate Moss' fugly boyfriend, rocker Jamie Hince, won't be buying her expensive presents again anytime soon!

Turns out The Kills guitarist bought her an over $4,000 ring for Christmas. But, just three hours later Cokate lost the ring! She apparently sold it for drugs ("misplaced" it).

A source says, “There was a terrible panic when Kate realised the ring had disappeared."

Well, itturns out the ring isn't easily replaceable.

Hince reportedly had it specially made for her while he was touring in the U.S.

Kate then spent hours trying to find it at home. She supposedly almost missed her flight trying to find the ring.

Moss, Hince, and her daughter are heading to Thailand for New Years.

Such a mess that Cokate!
