So while Russell Brand is having all that fun with a few "friends with benefits", Katy Perry herself is getting in deep with John Mayer. Does it look like this is going to last? A source told Life & Style:
"Katy and John never left each other's side and were flirting and affectionate the entire time. Katy loved it!"
"I'd say Katy's more serious with John than she was with [her ex, Florence + the Machine guitarist Robert Ackroyd ]," says a source, who spotted the couple at a pool party this past weekend. "Everyone knew they were coming together as a couple ... Maybe he's a changed man, but Katy likes bad boys. I can't imagine John's changed that much."
But John hasn't changed at all, he's always like that when it comes to women, right up till the point he decides there are other hotter women out there.
