Lady GaGa wasn't about to let Kim Kardashian and Miley Cyrus have all the fun on Halloween - stripping off to go as Princess High the Cannabis Queen for the occasion.
The Poker Face star went topless with only a pair of green sparkly cannabis leaves protecting her modesty, while also sporting a long, green wig and a green tutu to complete her outfit.
GaGa then wore the tiny outfit out partying with her make-up artist pal Tara Savelo, who took to Twitter to write: "For Halloween gaga threw us a rave xoxo."
Savelo - who dressed as Lady G from her Judas music video - then tweeted a snap of herself with the Marry The Night singer, who playfully poked her tongue out at the camera.
Before showing her fans her costume, the eccentric star teased her followers with a image of her transformation, accompanying the pic with the caption: "slowly revealing my halloween costume…"
Lady G later tweeted: "So i was weed for halloween. BEST COSTUME EVER ITS SO FUN. Princess High the Cannabis Queen. Photos of party on http://littlemonsters.com shortly.
"And NO 'shortly' is not the new 'SOON.' *searches for camera USB in hotel robe with bad hair and hangover.* last night was paradise."
