In celebration of her newly-released 1989 album, Taylor Swift and Diet Coke partnered with iHeartMedia to co-host a live broadcast of On Air with Ryan Seacrest on Thursday.

Over the course of Taylor’s four-hour radio takeover — which she dubbed the “TAYkeover” — the 24-year-old answered calls, gave fans relationship advice, discussed her all-pop album, and of course, danced to the playlist during her off-air breaks.

When “Black Widow” by Iggy Azalea and Rita Ora was gracing the airwaves, the “Shake It Off” singer lip-synced the track while performing an interpretive dance number filled with hilarious hand movements and facial expressions.

Taylor’s 1989 album, which is projected to sell over 1.2 million copies during its debut week, is available on iTunes here!
