London: She is famous for her outlandish hairstyles and clothing choices.
And now, Lady Gaga has caused a stir yet again by posting a picture online which shows her stripped to her bra and sporting green armpit hair.
The pop superstar has set up her own style blog in recent weeks called Amen Fashion, which documents her wacky outfits and photoshoots.
One picture in particular shows Gaga reclining on a toilet wearing a green wig, black bra and slashed denim shorts, and one arm is stretched above her head to reveal a shocking green patch of hair, reports the Daily Star.
The picture is titled `Private In Public`.
