Here is Christina Aguilera leaving a restaurant in LA and looking very serious. She is holding hands with her boyfriend Matthew Rutler, who was looking equally as serious. Just last night Christina performed on stage at the American Music Awards. She performed the song Moves Like Jagger with Adam Levine from Maroon 5. Christina and Adam met whilst working on the US talent show The Voice. They got on very well and decided to do a song together, which turned out to be one of the biggest hits of the year. Christina confirmed last month that she will also be back for a second series of The Voice. She said: 'I had to come back and do a second season of The Voice. 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.' The show works where the judges cannot see the auditonees so the judging is done fully on the voice. The show is also soon to be made for the UK, but with different judges. Christina is said to be a little bit stressed at the moment, as the man from Florida who has allegedly stolen pictures from the mobile phones of stars like her and Scarlett Johansson pleaded not guilty to the hacking at the start of this month. Nude photos of Scarlett were leaked onto the internet, but let's face it, with some of the outfits Christina has worn in her videos over the years, not a lot can embarrass her really!
