The former America's Next Top Model judge was loaned $20,000 (£12,500) worth of gems from Effy brand bosses to wear on the runway at The Reality of FASHION The Reality of AIDS show.

However, after strutting down the catwalk, an absent-minded Dickinson forgot to return the pieces, which included two diamond bracelets.

A source tells the New York Post's gossip column Page Six, ""She left with thousands of dollars of jewellery still on.""

Dickinson is adamant she never meant to take the pieces, telling the publication, ""If you're insinuating anything funny going on, you're barking up the wrong tree.""
