John Mayer: Jennifer Aniston Had My Back at Oscars

The singer reveals how sweet his girlfriend was to her date at the Academy Awards

No wonder Jennifer Aniston received so much affection from John Mayer on Oscar night.

It turns out that while the singer was happy to provide "moral support" to his girl at the Academy Awards, he was also "very, very nervous" about attending.

"It's not my world, the Oscar thing," Mayer told Ryan Seacrest on his KIIS-FM show Wednesday. "But [Jen] was so sweet to me that night, because you can go from a Grammy winner to a water boy when you walk into the Kodak Theatre on Oscar night." He added, "While it was really, really fun, the whole thing is very odd to me."

"I basically stepped into the picture frame of Hollywood," he explained. "And you have to really be with someone you know has your back in that situation, and she did, and it was really great."

As for why the normally low-key couple chose such a high-profile event to go so public with their relationship, John told Ryan, "At some point, you feeel comfortable and say this is the choice I want to make. I think a year is a pretty good period of time with which to say, yeah, let's go have a really good time at the Oscars."
