Lady Gaga steams up concert with X-rated romps

British pop star Lady Gaga set the stage on fire with a series of X-rated simulated sex acts during a concert.

Gaga sent temperatures soaring at her New York show Thrusday, stretching out on a dancing boy's lap while he went on feeling her with both hands, reports thesun.co.uk.

The singer was also groped in front of the audiences. She was also seen indulging in a mock threesome on stage.

Complementing her raunchy romps was an endless stream of wardrobe changes, the highlights of which included a kinky Samuri costume and a sparkly top fitted with shoulder pads.
