Lucky concert goers were treated to a special surprise during Demi Lovato‘s Summer Tour concert in Los Angeles, California on Wednesday night (July 18).

The “Give Your Heart A Break” songstress told the audience, “I’m so nervous. I’ve got friends in the audience and my family is here.” before adding, “Luckily some of my friends are going to help me out tonight on stage.”

Shortly after, Demi brought one of her celebrity friends on stage, Nick Jonas, to sing “Catch me” from her album Here We Go Again, much to the delight of the crowd, who went absolutely wild!

Following the concert, Jonas took to Twitter to write for his 4 million followers, “What a special night being able to sing with my friend @ddlovato once again.”
