John Mayer Doesn't Know Robert Pattinson From Tyler Rashton

John Mayer is so out of touch with the teens and tweens of today that he doesn't even know who Robert Pattinson is. What a dag...

The 31-year-old musician is feeling old because the whole Twilight phenomenon has largely passed him by.

"I've never seen Twilight, but it seems as if there are 90 lead actors I don't know in this film? Tug Tillis, Boan Joaner, Jared Vorak...Kelly Loargaarten, Keith Wells, Elizabeth Henley-Harrison, Erik McMcinson, Kyle Froam, Tiffany Grunch," he Tweets.
 
Still, it sounds like he's got a gist of things. He adds: "It's like you wake up in the morning and read 'Tyler Rashton: 'Tilly and I are just friends!' And then you just feel old."
