Music Stars of the '80s: Where Are They Now?

They were the teen queens of the 1980s pop scene, Tiffany and Debbie Gibson, the singing and fashion icons who rocked their rivalry all the way to pop-star superstardom before fading away as adulthood and the 1990s beckoned.

Now the former hit-making rivals are back and on tour together, bringing the decade that made them famous to the "Good Morning America" Summer Concert Series stage in a live performance today in New York City's Central Park.

Calling their tour "Journey Through the 80s," Tiffany and Debbie, who also starred together in the film "Mega Python vs. Gatoroid," perform a mix of their own material with covers of hits by Stevie Nicks, Reba McIntyre and Guns N' Roses from the decade they dominated.

The jean jackets, scrunchies, hairspray and hoop earrings of the '80s may be long gone, but the memories aren't.

While Tiffany and Debbie Gibson send '80s fans wild with their reunion today on the "GMA Summer Concert Series" stage, here's a look back at the rest of your favorite music stars from that glorious decade, and where they are now.
