Former Pop Star Rivals Christina Aguilera & Jessica Simpson Partied Together In The Name Of Linda Perry!
Turns out, it was a pretty poppin' party!
"Ashlee and Evan [Ross] acted like newlyweds. They were cuddled up together in a booth, laughing and showing off cute PDA. Jessica looked really happy to be hanging out with them and seemed to get along great with Evan. Eric [Johnson] and Jessica did their own thing at the party and would check in on each other every now and then. He came over to introduce himself to her friends a few times and would run close to the stage to take photos of the performances."
As for the returning Voice judge, she pushed through her sickness to support Perry:
"Her fiancé [Matt Rutler] held her hand on the way up. She said she was getting over the flu but wanted to come and support Linda."
