Let's hope it doesn't catch on! Lady Gaga sports bizarre flesh-coloured facial horns

She's known for pushing the envelope when it comes to clothes - but Lady Gaga is taking her look to a whole new level if her latest make-over is anything to go by.

The star appeared on Jay Leno's U.S. chat show last night with her face covered in flesh-coloured spikes that look like subdermal implants - the latest craze for people into extreme body modification in which metal shapes or even items of jewellery are implanted under the skin.

However, her spokesman told MailOnline 'no comment' when it came to whether the star had actually had them surgically implanted, or whether they were just convincing prosthetics.

All angles: Lady Gaga was sporting facial furniture to make it look like she'd had subdermal implants on Jay Leno's U.S chat show

Spiky: The singer's spokesperson wouldn't confirm whether or not the implants were real or just convincing prosthetics

Chat: The star was a guest on Jay's Tonight Show, but the chat show host made no mention of the singer's unusual new facial features

The star didn't mention them on the show however, on which she appeared Wearing just her underwear underneath a long sheer hooded cloak and with a black PVC horned eyemask - clutching the three Grammys she won on Sunday.

However, she removed the eye mask halfway through the interview to reveal the angular additions to her face, with two at her temples, two on her cheekbones and one on the bridge of her nose.

The overall look was not dissimilar to the character Kryten, a robot from sci-fi comedy Red Dwarf. 

Busting out: Sofia Vergara was also a guest on the show and said she'd upped her game when it came to her outfit when she found out who her fellow guest was

However, having transdermal implants can be extremely dangerous as with any foreign body inserted into flesh and are one of the riskiest forms of body modification.

The procedures are also often performed by body artists with no medical training for what is essentially a surgical procedure comparative to plastic surgery.

Maybe her new look was inspired while under the influence of marijuana, after her revelation just before the Grammys that she uses the drug.

Speaking on CBS 60 Seconds, which aired before the awards ceremony on Sunday, she said: 'I smoke a lot of pot when I write music. I'm not gonna, like, sugar coat it for 60 Minutes that, you know, I'm some, like, sober human being, 'cause I'm not.

'I drink a lot of whiskey and I smoke weed when I write.'

Back to Leno, and his other guest was actress Sophia Vergara, who said she'd thought carefully about what to wear after she'd heard who she was sitting on the sofa with.

Talking about her busty leopard print frock, the actress said: 'I tried to step it up a notch today because I knew Lady Gaga was coming. What do you think?'she grinned.

'I think she stepped it up two notches,' the singer quipped.

The Bad Romance singer also revealed that she totally scrapped her Grammys routine for new single Born This Way just two days before the event including all the costumes for her entire crew - reinventing the entire performance over 48 hours.

The resulting performance was seen by more than 26million people in the U.S. alone and she revealed of her celebrations afterward: 'I don't remember very much. I know it was fun. I do remember being called 'Drunky Gaga at some point.'

Out there: The star was wearing a black PVC eyemask which she later whipped off on the show to reveal her angular new face

Of her last minute change of plan, she explained: 'Two days before the performance I changed everything as I didn't like the clothing.

'I re-designed everything, but The House of Gaga were up all night and red eyed.'

She also revealed that she had got backing from Madonna for her single - despite many people pointing out the similarities between Born This Way and the Queen Of Pop's hit single Express Yourself.

Gaga said: 'There is really no one that is a more adoring and loving Madonna fan than me. I am the hugest fan personally and professionally.'

Not shy: The star performed in little more than her underwear at record label Interscope's official Grammy after party in Los Angeles on Sunday night

Performance: She'd stared off wearing something like a nun's habit before stripping down to her scanties

'The good news is I got an email from her people and her sending me their love and complete support on behalf of the single. If the Queen says it shall be, then it shall be.'

The star also talked about her debut on the cover of Vogue with yet another new look.

Host Jay pulled out a copy from under his desk to show Gaga, which she said was the first time she had seen a physical copy.

She exclaimed: 'I hadn't even seen it in real life! I was so excited! It's a girls dream to be on the cover of Vogue.'

Her appearance on the chat show however was mostly to talk about her new single Born This Way, which she performed at the Grammys, as well as her forthcoming self-titled album, due out on May 23.

She said of the record: 'It's eclectic in a way, the rest of the songs are quite different to Born This Way, it grows and changes and has amazing themes and I had so much fun writing it.'
