LADY GAGA has taken her pledge never to be seen in normal clothes to a dangerous new level.

The crackpot US singer had to be undressed by cabin staff on a flight from London to America after her legs began to swell due to another odd outfit.

Bonkers GaGa had boarded a long-haul flight at Heathrow wearing black and yellow TAPE and giant blue shoes designed by her pal, the late ALEXANDER McQUEEN.

Her daft garb was so uncomfortable it brought on the early stages of the potentially deadly deep vein thrombosis.

Heavy metal ... Lady GaGa in another odd outfit

The experienced flight crew told GaGa she'd best get it off quick or risk long-term damage. Only last week GaGa had boasted to TV host JONATHAN ROSS of the lengths she would go to to avoid wearing comfy clothes.

She insisted: "I would rather die than have my fans not see me in a pair of high heels. I'd never give up my wigs and hats for anything."

When a pop star risks gangrenous limbs for fashion, you can't knock that. MADONNA seems dull by comparison.

Lady GaGa, whose Poker Face hit top spot a year ago, is pictured here in another set of madcap outfits from her video to latest single Telephone - her collaboration with BEYONCE.

Director JONAS AKERLUND has continued the story from where the quirky Paparazzi vid left off.

Lady G is now locked up in jail for killing her boyfriend - but is having a great time and doesn't want to leave.

But the idea of GaGa settling down for an eight-hour flight to New York in huge blue heels is priceless.

An airline source said: "GaGa was a high-risk DVT case so she was advised to change out of her clothes. But the outfit was so cumbersome she needed help changing out of it. She was particularly miffed about ditching her heels. She was wearing them in memory of her friend Alexander."

It was an unusual trip even without GaGa's health scare.

The singer had waited to board in the posh Concorde Lounge of Terminal 5 with LIAM GALLAGHER, P DIDDY and the GELDOF sisters.

That group definitely have a story or two to share about fashion nightmares.

When GaGa appeared on the Jonathan Ross show they chatted about Slankets - blankets with sleeves. And she even gave him one as a gift afterwards.

Sounds like she'd have been better off wearing one of the cosy covers on the flight. I'm sure her fans wouldn't be too offended.
