Taylor Swift, Ariana Grande, Kelly Clarkson Perform at the 2018 Billboard Music Awards (PHOTOS)

In the event the onset of summer didn't do the trick, the performers at the 2018 Billboard Music Awards certainly heated things up Sunday night (May 20).

The show, hosted by Kelly Clarkson, included a number of fantastic sets — everything from Clarkson, herself, performing from behind a collection of Vegas showgirls to Ariana Grande sprawled across umbrellas as she delivered her set.

Clarkson and Grande joined Salt-N-Pepa with En Vogue, Dua Lipa, Jennifer Lopez, John Legend, Macklemore and Kesha, Zedd, Maren Morris and Grey, Khalid and Normani Kordei, Shawn Mendes, Christina Aguilera and Demi Lovato, BTS, Camila Cabello and Pharrell, and Janet Jackson as performers.
