Justin Timberlake reveals he hooked up with a Spice Girl on Ellen... but leaves audience guessing

Justin Timberlake has revealed he hooked up with a member of the Spice Girls earlier in his career.

The 37-year-old singer was joined by the members of NSYNC on the Ellen DeGeneres Show when he made the revelation.

During a round of game Never Have I Ever, DeGeneres quizzed the group: “Never have I ever hooked up with a Spice Girl.”

All the members of NSYNC quickly turned their paddles to ‘I have never’, with the exception of Timberlake who hesitated.

The red-faced singer hesitantly turned his panel to ‘I have’ after a prompt from the host.

He was quick to keep mum about all other details regarding which member of the girl group it was.

The rest of the group went on to reveal that they had also hooked up with fans in the past, joking that some of them had wives who are fans of their music.

The news comes after NSYNC reunited to receive star on the Hollywood Walk of Fame.

Timberlake reunited with Lance Bass, JC Chasez, Joey Fatone and Chris Kirkpatrick for the unveiling of the star on Hollywood Boulevard on Monday.

"We're really a family," Timberlake, 37, said, addressing the crowd. "I don't really think I could put into words how much the four of you mean to me. ... I just love all of you so much," he added.
