Christina Aguilera & Matthew Rutler: Mozza Mates

Christina Aguilera holds hands with boyfriend Matthew Rutler while leaving Osteria Mozza on Thursday (November 17) in Los Angeles.

The 30-year-old entertainer will be hitting the stage at the American Music Awards this Sunday with her Voice co-coach Adam Levine – they’ll be singing their smash hit “Moves Like Jagger”!

“I had to come back and do a second [season of The Voice],” Christina told Access Hollywood late last month.

“How could I not? This is the most exciting show – ever! The suspense value? It’s intense. I think I get more nervous in these blind auditions than the actual artists and vocalists that come up here to audition. It’s nerve wracking and exciting,” she added.
