Pop star Dannii Minogue has been hurt by newspaper revelations of a lesbian sex romp, according to a close friend.

Images published by The News of the World over the weekend, apparently show the little sister of Kylie Minogue, in steamy and sexual poses with a stripper at the Puss In Boots nightclub.

The newspaper claims the CCTV images show her kissing Jupiter and thrusting her face into her chest. They say the images were taken last September.

A friend of Miss Minogue’s told the Sun, “They were having a laugh. Dannii is hurt.”

The Puss In Boots club is understood to have a strict “no touching” policy, with patrons required to stay at least 1m from strippers. Under UK licensing rules, strip clubs must have in-house security cameras switched on at all times and bouncers must monitor them.

Further reports suggest the stripper’s parents had no idea of her profession. Her mother told the Sun, “We didn’t know what she did, it’s come as a shock. My daughter is in bits.”
