Fans of Australian singer Dannii Minogue were left stunned after the singer's recent romp with a naked female lap-dancer at a London club was caught on tape by the CCTV security camera in the club.

According to a source, while at the 'Puss In Boots' club, Kylie Minogue's little sister indulged in a sex romp with a busty blonde stripper in full view of the club's other visitors.

"Dannii was having the time of her life and didn't care who saw. She wasn't in a private booth or the VIP area, she was on the dance floor," NewsoftheWorld quoted the source, as saying.

"I can't believe how far they went. It was more like a porn film. There were hands and tongues everywhere-I thought it was going to turn into a full-on orgy," the source added.
