OK, Taylor and Selena — it was only a matter of time before we figured you two out. The singers showed up to the Grammys [1] in bright outfits, claiming it was "girls' night," but we think we know what movie they'd be watching if they had stayed home: 10 Things I Hate About You [2].

Seriously — just see how Taylor's Atelier Versace coordinates [3] match up to Bianca Stratford's crop top prom look. And is it really a stretch to say Selena worked her glittering Calvin Klein design [4] because it was midnight blue, the exact shade of Kat Stratford's formal dress? We think not!

Read on to see the hilarious comparison that's got the Internet buzzing, then weigh in and let us know if you think Taylor and Selena channeled Larisa Oleynik's and Julia Stiles's characters in the famous flick.
