Gay rights supporter Miley Cyrus simulated a lesbian kiss with a dancer while performing on last night’s Britain’s Got Talent.

The straight star was seen thrusting her lips towards the female dancer during an energetic performance of her new song Can’t Be Tamed.

The fake kiss has been compared to the embrace between Britney Spears and Madonna at the 2003 MTV awards.

Cyrus is a gay marriage supporter. She recently revealed she had received hate mail for her stance and had to delete her Twitter account because of the abuse.

The 17-year-old recently attracted disapproving headlines after being pictured “dirty dancing” with an older man. He turned out to be producer Adam Shankman, who is gay.

While Cyrus is unlikely to be criticised for the post-watershed performance, a similar show by gay American singer Adam Lambert last year led to his television appearances being cancelled.

More than 1,500 US viewers complained when he kissed a man and simulated oral sex at the American Music Awards in November.
