Trend alert! Celebs love on-stage underwear

From Britney Spears to Lady Gaga, everyone's stripping off on-stage and performing in the most luxe of lingerie

Jennifer Lopez and Lady Gaga wowed the crowds with performances at the American Music Awards, both showcasing the hottest new celeb trend for on-stage underwear.

J Lo kick-started an energetic rendition of her newest track Louboutins, wearing a gold stuctured furturistic frock - but halfway through her performance, whisked it off to reveal a racy lace number underneath.

Next up, and Lady Gaga was the second star of the night to hit the stage in her smalls, and was strutting her stuff in a wonderfully Gaga-esque ensemble of nude bra and knickers, covered with plastic bones. 

And they're not the only stylish singers to have jumped on the underwear-as-outerwear trend of late - with everyone from Beyonce to Britney having eschewed cover-ups in favour of hold-ups. 

Miss Knowles took to the stage at the MTV Europe Music Awards last month in a raunchy red leotard and suspenders, while Lady Gaga also opted for a racy rouge look during a recent television performance.

Similarly,Britney Spears' Circus tour sees her showing off her moves in a series of scantily-clad costumes, while Katy Perry took to the stage at V Festival in a jewel-encrusted bra and high-waisted hotpants.
