Gaga's wig leaves Katy and Nicki in the dust in Tokyo
Her outfits are wildly hit and miss, but when Lady Gaga gets it right it's clear that she's the queen of the gimmick.
Nicky Minaj and Katy Perry might dye their hair pink and blue but they never looked as good as Gaga did when she arrived in Tokyo today.
Japan is, of course, where this bright trend originated, so it was key to work it properly, and the 25-year-old managed this with aplomb.
Gaga, real name Stefani Germanotta, worked a huge pony tail riven with pastel rainbow tones.
She paired it with a long studded jacket (one of the key trends of the season) and brilliant black talons and large sunglasses.
This helped her to look like a rock star, which is hard with pastel hair... just ask Katy Perry.
It's a look pioneered by her only real peer, the still fabulous in her Fifties Madonna, who sprung into the spotlight with pink hair paired with a leather jacket.
Her Little Monsters, of a certain age, should all want to dress in a diluted version of this style.
When she left Hong Kong to head to Japan, she was also wearing a fabulous - if less likely to be copied outfit.
With her hair bright yellow and in a side knot, Gaga looked like the bride at 1940s themed wedding in the future by donning a stunning Versace gown, replete with stack heels.
She's gearing up for the Japanese leg of her Born This Way Ball Tour, and was greeted by hundreds of her adoring little critters as she headed through the airport towards her own pot of gold.
Lady Gaga is particularly beloved in Japan thanks to her efforts to help out after the massive tsunami and earthquake disasters.
A Gaga teacup was auctioned off for $75,000 to help rebuilding efforts.
