Kylie Minogue shocked Tv producers by pulling some raunchy moves with one of her contestants on the U.K. version of The Voice.

Bosses at the Bbc had to edit footage so the Australian judge's actions cannot be seen from the waist down because they deem her bottom grinding moves too raunchy for the show.

Minogue has been flirting with British rapper Leo Ihenacho - formerly from The Streets - since his first audition and the chemistry has stepped up while rehearsing behind-the-scenes.

A source tells Britain's The Sun newspaper, "Kylie and Leo have great chemistry, but they got a little carried away and it became lapdance-esque. There are certain grinding scenes that we've only shown from the top up.

"Her skirt was way too short for a full-length shot! The angles had to be very carefully considered."

During the footage - broadcast in the U.K. on Saturday (01Mar14) - Minogue makes a sexual reference to Ihenacho, asking him if he has a "thunder down under".
