The old meets the new on the ABC music series, which debuts June 30.
RIP Christina Grimmie.
Khloe Kardashian, Kourtney Kardashian, Jessica Alba, Laverne Cox and Meghan Trainor were all there!
Other stars partied at JLo's Planet Hollywood show after the awards.
Trainor also dished to ET's Katie Krause about her day at Disneyland with Brooklyn Beckham and Chloe Grace Moretz.
She killed it, 'No' question!
She's all about that place, 'bout that Happiest Place on Earth.
The 'All About That Bass' singer opens up to ET at 102.7 KIIS FM's Wango Tango about her recent mishaps.
It's all about that waist.
A lot has changed since Meghan Trainor first brought us the 'Bass.'
The star has since revealed she actually asked the show to keep in her mistake!
The "All About That Bass" still think she "killed" her performance.
The 22-year-old gets hilariously candid about what she will and won't tolerate in a boyfriend.
The 22-year-old pop star's sophomore album, 'Thank You,' is out May 20.
