The "Shake it Off" pop star and the "Suit & Tie" singer sat next to each other at the 2015 iHeartRadio music awards, and when Swift won the Best Lyrics award for her hit song "Blank Space," she absolutely freaked out in the most adorable way possible.
As it turns out, the two actually staged a cute practical joke. When Swift won, Timberlake freaked out alongside her. They pretended his name had been called and he even started to walk toward the stage.
Apparently, the two are kind of close. Swift even appeared in the pre-recorded tribute to Timberlake that played when he won the iHeartRadio innovator award, saying, "I'm Justin Timberlake's biggest fan. I know all his songs."
