Justin Timberlake, who last year bailed on 'N Sync's reunion album, is now not ruling out a reunion with his former boy band.
"There's still a chance that 'N Sync could get back together," Timberlake, 24, tells TV's Extra. "There's a chance that Lance could still walk on the moon."
The latter comment refers to bandmate Lance Bass's longtime desire to fly into space. (Bass, 25, finished formal Russian Cosmonaut training but has, so far, never been able to raise the $20 million required for the ticket into the stratosphere. MTV News reports he's still gathering funds.)
Despite the seemingly sarcastic tone, Timberlake apparently wasn't being fresh about his comment about the group. Speaking of his onetime bandmates – Bass, JC Chasez, Chris Kirkpatrick and Joey Fatone – Timberlake said: "Our relationship goes way deeper than records. We're friends, those are my brothers."
Last July, the five sang the national anthem at a charity event in Miami, prompting talk that the guys would gather in a studio to begin work on a long-awaited new album.
But then, an insider told PEOPLE at the time, Timberlake told his bandmates that he wasn't interested in being a part of the next 'N Sync album. "Justin said he's not in the mood and doesn't think it will work," said the source at the time. "He doesn't want any part of it."
