Dueling 80s popstars Tiffany and Debbie Gisbon shared the stage today on "Good Morning America" -- where they performed some of their classic hits, with a twist.
Gibson, wearing an outfit from Britney Spears' closet circa 2001, sang "Only In My Dreams" -- and surprisingly added a rap to the middle of the song, which she performed while surrounded by backup dancers.
Tiffany was a little more low key with her solo, singing a countrified version of "I Think We're Alone Now."
The duo also sang Journey's "Don't Stop Believin'," The Go-Go's "We Got the Beat" and Heart's "What About Love."
The two kick off their "Journey Through the 80s" tour tonight in NY.
