The Spice Girls and the Backstreet Boys may be uniting for concert that would be a dream for 90's music fans. Brian Littrell of the Backstreet Boys hinted that the two groups may join forces for a world tour.

However don't get your hopes up as of yet. The tour is just in the talking stage and there's only a "maybe" that it might happen.

"We are actually in early talks about maybe doing a world tour together with the Spice Girls," BSB's Brian Littrell old U.K. newspaper The Sun.

It wouldn't be hard to get the Backstreet Boys together for such a tour. The boy band has been doing tours for the past several years. Their next tour if the A World Like This Tour which kicks off in May. They'll also be going on another cruise in October in which fans can join them.

Getting the Spice Girls together may not be so easy. At least not every member. One member that would most likely be on board is Mel B. In a recent interbiew with MTV News, Scary Spice said she'd love to have a reunion in 2014 as it will be the group's 20th anniversary.

"It will be our 20th year anniversary next year so I'm hoping we do get together and do something," Mel B told MTV News. "It kind of would be a shame if we didn't."

One member that most likely wouldn't be on board is Victoria Beckham, or Posh Spice. In an interview with Vogue Paris, she said her Spice Girl days are behind her.

"I realized it was finished for good in 2008, when we reformed for our reunion tour," Beckham told Vogue Paris. "It should have been the best moment of my life, but I just wanted to be elsewhere. It wasn't a lack of respect for the girls or the audience, but the passion just wasn't there."

The last time the Spice Girls reunited was for a quick performance during the closing ceremonies of the 2012 London Olympics.
