Debbie Gibson and TiffanyThe '80s pop scene was ruled by two teen queens, Tiffany and Debbie Gibson. The former hit-making rivals announced that they are teaming up to go on a tour together, themed after the decade that made them famous.

"We want to journey through the '80s and all the artists who influenced us," Tiffany told New York Post.

She and 'Mega Python vs. Gatoroid' co-star Gibson will cover hits by the decades' icons, including Stevie Nicks, Reba McIntyre and Guns N' Roses.

Tiffany, now 39, sky rocketed into pop super-stardom overnight with her 1987 dance hit 'I Think We're Alone Now' from her debut album 'Tiffany' -- while Gibson, 40, topped the charts with hits including 'Lost in Your Eyes' and 'Electric Youth' from her 1989 'Electric Youth.'
