Both Tiffany Darwish—better known in the global music scene as Tiffany—and Debbie Gibson started their careers in the ‘80s, topped the charts and sold millions of records in their teens.

Tiffany released her eponymous debut album at age 15, featuring the hit single “I Think We’re Alone Now,” which topped the Billboard Hot 100 list in 1987. A few years later jumped back up there with “Could’ve Been,” which peaked at the No. 1 spot in February 1988, effectively cementing her status in that era.

Thereafter, Tiffany cut hit after hit with “All This Time,” “If Love Is Blind,” “Hearts Never Lie,” and “It’s The Lover.”

Gibson, meanwhile, released her debut album Out of the Blue in 1987, which spawned several international hits such as “Out of the Blue” and “Only in My Dreams.” The singer-song writer also released “Foolish Beat” from the same recording, which made her the youngest female artist, 17 at that time, to write, produce and perform a Billboard Hot 100 No. 1 single.

With their major achievements in the music scene, it came as no surprise that Tiffany and Gibson were pitted against each other at the height of their careers. But nowadays, four decades since they lorded over the charts, these American ‘80s music stars enjoy a good laugh at their supposed rivalry.

“There’s no such thing!” Gibson exclaimed on Thursday where she and Tiffany shared the spotlight to talk about their first Philippine concert tonight.

“I just only remember, it was such a relief when I’d run into Tiffany if we were doing ‘Top of the Pops’ [a UK music show]together or whatever. I’d feel like, oh she’s the only other girl on the planet doing what I’m doing right now. There was just this instant camaraderie and rapport between us,” the now 48-year-old Gibson shared.
