*NSYNC star Justin Timberlake reveals he once 'hooked up' with a Spice Girl

Justin Timberlake has spilled that he once hooked up with a member of the Spice Girls.

The pop heartthrob and his *NSYNC bandmates - Chris Kirkpatrick, Lance Bass, JC Chasez and Joey Fatone - took part in a game of Never Have I Ever on The Ellen DeGeneres Show when they appeared for an interview following the boy band being honoured with a star on the Hollywood Walk of Fame.

During the game, the guys had to respond either "I have" or "I have never" to the statement "never have I ever hooked up with a Spice Girl".

Whilst four members turned their paddles to read "I have never", Justin hesitated to turn his to reveal his answer was "I have", prompting Ellen to place a paddle with those words on his knee forcing him to turn his own too.

Whilst four members turned their paddles to read "I have never", Justin hesitated to turn his to reveal his answer was "I have", prompting Ellen to place a paddle with those words on his knee forcing him to turn his own too.

During the fun game, Justin asked: "Why is every question, have I ever hooked up?"

Although he revealed he'd had a fling with one of the five girls - Mel B, Emma Bunton, Victoria Beckham, Mel C and Geri Horner - the 37-year-old singer did not tell Ellen which one it was he bedded.

During the game, the *NSYNC boys also all admitted that they'd hooked up with someone on their tour bus, but none of them had made love to one of their own songs.

Both groups were popular at the same time in the 1990s and Victoria Beckham previously revealed that the two bands first met at an airport in Germany.

During an interview on The Late Late Show with James Corden last year, she said: "I wouldn't say that I was obsessed, but when we were in the Spice Girls, we were in Germany doing some road show and we were sitting there in an airport, five girls, all together. Some guy comes up and he says, 'Hey! I'm in a band. I've got my friends. Can we come sing for you?' They stood there and they could sing! And it was *NSYNC and that was Justin Timberlake. They shut us up because they were good!"

Apparently, it was Emma Bunton, aka Baby Spice, who 'hooked up' with the former *NSYNC boy bander.

In a 2004 interview with Johnthan Ross, Emma admitted that she had a fling with Justin, saying "we've been hanging out and having fun. 

"We partied a bit, he was very sweet."
