Lady Gaga is known for her outrageous fashion statements and left little to the imagination this weekend in London.
Stepping out in the white see-through bodysuit, the Applause singer didn't seem to care as the paparazzi caught her naughty parts on camera.
Gaga was leaving Boujis nightclub in London after her Itunes performance this weekend -- and the top of the onesie was so sheer that everyone could see her chest and nipples. Oops! (See the photos.)
Meanwhile, Gaga shed her wig onstage at the iTunes Festival in London on Sunday, telling fans she had been using "wigs and make-up" to "cover up the pain."
She announced to the crowd: "When I didn't feel strong enough to be me, I created someone else. And it worked. So here I am, the human underneath the wigs... This is my real hair."
Lady Gaga Without Makeup
She removed the wig to reveal her natural brown tresses.
During the concert, the pop star performed seven new songs, as she headlined the event at London's Roundhouse Sunday night. The concert started with her swinging over the audience in a cage and involved many on-stage costume changes, elaborate wigs and dancers in hazard suits wearing pig masks, hanging from the ceiling.
The songs included Jewels & Drugs, a rap number featuring T.I., pop song Sex Dreams and ballad I Wanna Be With You.
Gaga's new album ARTPOP will be released Nov. 11. She premiered the single Applause live at the MTV Video Music Awards last week.
