Grohl was on hand as a presenter for the American Music Awards on Sunday night. Not sure if the pic above was before or after co-presenter Joan Jett grabbed his ass. Wow, she still looks great at 55. They were there to present Imagine Dragons with the Favorite Alternative Band award. He also found time to chat with Rolling Stone [click here to see article]. He says he's excited about the new Foo's album in it's early stages and that they're trying something that, to the best of his knowledge, has never been done before. It could be anything. Here's a guy that's constantly evolving, trying new things and releasing timeless albums. In a time where rock isn't at it's peak, I'm confident that the Foo Fighters will release another album next year that people get excited about and listen to for more than just a week, before getting bored and moving on to something else.
