Weezer has a song on The Red Album called "Heart Songs" that pays tribute to artists and songs that they like. However, they incorrectly say, "Debbie Gibson, tell me that you think we're alone." They seem to be confusing that with the song "I Think We're Alone Now," by the Shondells, and covered by Tiffany.
So let me clear some things up for the good of humanity. Debbie Gibson, for the most part, wrote her own songs and could play several instruments. Tiffany couldn't play anything, wrote almost nothing and covered a lot of tunes. Confusing the two of them is like a crime. And having seen both live, Tiffany can't sing to save her life, while Ms. Gibson can.
Plus she was much hotter in Playboy, because Tiffany had grotesquely large fake boobs.
