Lady Gaga's male alter-ego Jo Calderone is featured on the cover of her new single 'You And I', so to celebrate we've got pics of other pop stars who've raided the dressing up for a bit of gender-bending lolz.
Who: Kevin Rowland.
Why? Oh Geno...Kevin Rowland unleashed his femme side to an unsuspecting festival audience to promote his solo album from 1999 'My Beauty'. The Reading crowd didn't really appreciate this image over-haul and pelted him with bottles of wee.
Who: Nicky Wire.
Why? Wire likes to 'glam it up' and by that we mean 'dress up a bit like Dot Cotton nipping to the shops' during Manics shows.
Who: Twisted Sister's Dee Snider.
Why? Influenced by glam rock and really, really evil clowns, Dee Snider's look was re-popularised by Christina Aguilera in her 'Lady Marmalade' phase. Drrrrrrty.
Who: Ryan and Gary Jarman from The Cribs.
Why? The one-off single from the brothers saw the twins getting all dressed up as their female personas for the cover. Disturbingly Gary looks not dissimilar to Ryan's girlfriend Kate Nash.
Why? At a charity event for the Rainforest Fund the former Gordon Sumner decided to drag it up well from the head up at least. To make it more painful it was for a version of Journey's 'Don't Stop Believin''.
Who: New York Dolls.
Why? Pre-dating KISS, visually David Johansen and co were an epic mix of scary downtown toughness and far too much concealer for their own good.
Who: Mariah Carey.
Why? In the track she dissed Eminem's stalkerish tendencies, so for the video MC dragged up to look like the Real Slim Shady.
Why? Madge donned the male garb during her Sex book phase, possibly in an attempt to disguise herself from Vanilla Ice (who she was romancing at the time).
Who: Jeffree Star.
Why? This model/Myspace star/make-up 'artist' shows the others on this list how it's done. Pictured here sporting a Cher Lloyd-like barnet.
Who: Imogen Heap.
Why? For her duet with former Sneaker Pimps man IAMX ('Secret Friend'), Imogen Heap donned the man hair and stressed-out-business dude look for the video.
Who: Queen's Freddie Mercury.
Why? Freddie and the rest of his bandmates adopted female personas for their 'I Want To Break Free' video. A particularly effective Roger Taylor caused many a teenage boy to have a 'confused' moment.
Who: Foo Fighters' Dave Grohl.
Why? The Foos frontman ended up playing many of the characters in this video, including this geeky superfan.
Why? Andy and Vince went full on Agnetha and Frida for the video of their ABBA cover 'Take A Chance On Me' prompting a couple of decades of ABBA cross-dressing worship. Thanks guys.
Who: The Dresden Dolls' Brian Viglione.
Why? An early fan of The Rocky Horror Picture Show, the drummer went in drag to his 8th grade dance.
Who: Placebo's Brian Molko.
Why? Brian did the whole goth girl/boy thing during the band's 90s peak. That was until his hair started thinning. Now, not so much.
Who: Boy George.
Why? The patron saint of 80s drag, the Culture Club frontman came from the New Romantic/punk scene and brought the war-paint with him.
Who: Annie Lennox
Why? For the 'Who's That Girl' video, the singer ended up snogging the man-version of herself. Legend has it that she was stopped at US customs because they didn't believe she was actually a lady.
Who: Billy Corgan.
Why? Smashing Pumpkins frontman sports a rather unfetching dress during the Pumpkins comeback. Like David Beckham's sarong but worse.
Who: Kurt Cobain.
Why? Always in touch with his female side, Cobain was often seen displaying his femininity with a rather fetching frock.
Why? In 'The Real Slim Shady' video Marshall Mathers dressed up as Britney Spears at the VMA's whilst verbally dissing Christina Aguilera. Genius.
Who: David Bowie.
Why? He earnt the sobriquet 'The Dame' for his journeys into drag-dom. In truth, he looked a bit too much like Lulu for it to work.
Who: Grace Jones.
Why? Grace subverted the whole male/female thing with her short cropped hair and masculine image. Made chat show host Russell Harty cry.
Who Marilyn Manson.
Why? A fan of Bowie's, Marilyn Manson donned the frocks and hair dye because the whole 'Anti-Christ Superstar' thing wasn't shocking enough.
