"From what I've heard, they want to do their own tour. I think it's their 20th anniversary, were back in the studio making a brand new album, so everyone's doing their own thing," McLean explained.
However, the 38-year-old singer did leave the door open just a crack, adding, "God willing, down the road, maybe it could happen. But as of right now it's not happening. They're doing their thing, we're focusing on our thing. But I think it would be something awesome if it did happen."
McLean's bandmates, Nick Carter, Brian Littrell, Howie Dorough and Kevin Richardson, who joined him for the sit-down, tried to backtrack from shutting down the idea entirely, but it sounds like the mythical Spice Girls/Backstreet Boys team-up isn't in the cards any time soon.
On Wednesday, Mel B (a.k.a. Scary Spice) spoke with ET at a special Rooftop Cinema Club screening of Spice World in Los Angeles. The 41-year-old pop star opened about the possibility of a Spice Girls reunion, explaining, "It's an ongoing thing we keep talking about and it is our 20th anniversary, so we're going to do something. We're just trying to figure that out right now"
