This is her idea of casual wear!
Lady Gaga was spotted in London on Monday night, dressed in a leotard and neon green bikini bottoms.
We love this tranny!
The Just Dance singer apparently had a craving for some fish and chips, as she picked up some food to go - dressed like that! - on her way to a studio.
Gaga is currently rehearsing for her upcoming European tour, where she'll be opening up for the Pussycat Dolls.
She will wear even crazier shiz than that, we're sure!
