Strictly Come Dancing fans may soon witness a murder on the dance floor when Joe Calzaghe next meets his sexy dance partner Kristina Rihanoff.

By all accounts the former boxing champion had his hands “all over” at least five different girls at Mayfair's Mahiki nightclub on Saturday.

A fellow clubber at the venue told us: “Joe was acting like a single man. He was getting a lot of attention from different girls, and was acting like a child in a candy shop.”

Since 37-year-old Joe entered Strictly rumours have been flying that he has been dating Kristina, 32. They have been snapped holding hands and cuddling up together, and we've spotted them snogging in various nightclubs about town.

But in news that will almost certainly devastate Russian bombshell Kristina, our source continued: “Joe was sitting on a table with Rav [Wilding — who was voted off Strictly that night], and they were both really going for it.

“They were sitting with other pals, but their table must have got through at least five Treasure Chest cocktails, and they were both doing shots of Patrón Tequila and drinking champagne. Lots of pretty girls were approaching Joe, and he seemed thrilled when each new one arrived.”

Despite scoring a miserable 19 points, placing him at the bottom of the Strictly table, Welshman Joe was more than happy to show off his dance moves. The source continued: “Joe was dancing with quite a few different girls and touching their bodies.”

But Joe wasn't the only person dirty dancing at the weekend. Kristina had her hands full last night as she performed a one-off dance class at the Wandsworth Palais with Strictly colleague Brian Fortuna.

We can certainly see where Joe gets his hands-on style.
