Pop Star Lady Gaga failed to return four priceless items of lingerie

Pop star Lady Gaga is facing the wrath of bosses at an underwear company after she allegedly failed to return four "priceless" items of lingerie.

The "Poker face" hitmaker was reportedly sent seven undergarments from Rigby and Peller, which supplies underwear to British monarch Queen Elizabeth II, Gwyneth Paltrow and Sophie Dahl, among others.

Celebrifi.com reports that Gaga was sent the exclusive items on loan to wear in her next music video, but company bosses allege only three of the briefs were returned.

Executives at the company claim the underpants were prototypes for their 2010 autumn/winter collection unveiled at a fashion show May 3 and their loss could stall the production line.

"Obviously we were delighted that Lady Gaga wanted to use our new pieces in her next video, but we did stress we needed them back in plenty of time for our press show," said a spokesperson for the company.

"They are handmade, unique designs, simply priceless and not available anywhere in the world so we are really disappointed not to get them back for our major showcase of the year," the spokesperson added.

Gaga's spokesperson said, "We've nothing to say."
