Demi Lovato Joins Cheat Codes for 'Tonight Show' Performance! (Video)

We’re loving Demi Lovato and Cheat Codes‘ new song “No Promises,” so we were so happy to see them perform it together on television!

The music stars teamed up for a performance on The Tonight Show Starring Jimmy Fallon on Monday (May 22) at NBC Studios in New York City.

Demi took to Instagram that night to send her thoughts to the people of Manchester after the bombing at Ariana Grande‘s concert.

“I’m so sorry you had to go through this Ari.. This isn’t fair and nobody should have to go through this. My thoughts and prayers are with you and the victims. I love you so so so much,” she wrote.
