Justin Timberlake admits he hooked up with a Spice Girls and many speculate the mystery girl is Baby Spice Emma Bunton.

NSYNC, whose members are Timberlake, Lance Bass, Joey Fatone, JC Chasez, and Chris Kirkpatrick, was a guest on Tuesday on Ellen DeGeneres Show and fans pretty much had a lot of takeaways when they played the classic game Never Have I Ever. The game is pretty simple: Each has been given a paddle with two options, "I Have Never" and "I Have," which they'll use to answer the questions.

Tricky Question

Knowing the host, she threw in some hard-hitting questions that re-earthed some old dirt about the group. But what probably was the biggest question, that rendered to be a confirmation for that matter, during the game was if NSYNC members have ever hooked up with members of the Spice Girls. All of them answered "I Have Never," but Timberlake took quite a long pause and contemplated on the question.

DeGeneres then gave the answer for him, to which, for a brief moment, Timberlake also matched his paddle with "I Have." But that's only that as the 37-year-old crooner remained tight-lipped about the revelation, and in the game, he just continued playing without giving out details.

Bunton's Interview

While Timberlake did not spill who he had a fling with from the acclaimed girl group, an old interview with Bunton easily teased she is the girl in question. During the interview with Jonathan Ross, the host asked the blonde singer if she had a one-night stand with the now-husband of Jessica Biel.

"We hung out and partied a bit and he was very sweet. He spoke about this first, 'cause otherwise I would not have said a word. He's very sweet," Bunton divulged.

If that's true, it is safe to say that the tryst between Timberlake and Bunton is long over. The "Can't Stop The Feeling" singer is happily married to 36-year-old actress Biel since 2012. They were also blessed with a son, Silas Randall.

Moreover, Timberlake even brought The Sinner actress during NSYNC's reception of their Hollywood Walk of Fame a day before the group was a guest at the talk show. The patriarch also expressed his gratitude to Biel during his speech.

"And now, my beautiful wife, who's here today, now the mother of our beautiful son, I love you so much," Timberlake said.

As for Bunton, she and her fiancé, Jade Jones, have two children, Beau and Tate. She and the singer have been engaged since 2011.
