Katy Perry is facing court for making an "obscene" on stage gesture.

The 'Part of Me' singer was performing in India to mark the new Twenty20 cricket season when she invited Australian ace Doug Bollinger up to join her.

Katy asked him to show her how to hold a bat, so the 30-year-old sportsman stood behind her, wrapped his arms round her and as Katy held her microphone, he put his hands on hers and lowered the microphone to her groin.

Although neither of them knew the gesture would cause offence, a bid to prosecute Katy for lewdness was being pursued by the High Court in Madras.

The complaint filed by a lawyer slams the pose as "obscene and lascivious - appealing to prurient interest".

According to The Sun newspaper, Katy could be summoned to answer an indecency charge after judges rule on the accusation at the end of the month.

A source added: "They were only having a bit of fun but obviously it can be deemed offensive.

"It may have been a bit saucy given where they were - but this all seems a bit excessive."
