Last week, a whole bunch of amazing celebs turned up to the iHeart Music Awards, including Taylor Swift, who was a real-life mermaid.
The awards night went on without a hitch, minus the part where T-Pain made a joke about "headbutting" Taylor's boobs.

"This @TPAIN exchange w @taylorswift13 was the most awkward thing I’ve seen in the history of forever. #iHeartAwards2019 #eekface" one person wrote on Twitter.
