Musician joined his girlfriend at the prestigious event


John Mayer was worried about going to the Oscars with girlfriend Jennifer Aniston.

I was very, very nervous, he tells Us Weekly. It’s not my world, the Oscar thing.

‘You can go from a Grammy winner to a water boy when you walk in the Kodak Theatre on Oscar night. That’s just like a whole different level. [I just went for] moral support.

Jennifer, 40, presented an Oscar with Kung Fu Panda star Jack Black, 39, while ex-husband Brad Pitt, 45, and his new partner Angelina Jolie, 33, looked on.
