Since there's nothing else what to talk about right now... Let's say, there is infidelity with thought, there are infidelity dreams, there are good friends, there is a lot of crazy fans, there are stewardesses, there are singers, there are prostitutes, there are VERY private prostitutes, there is phone, there is webcam, there are e-mails, there are magazines. Also, he was an actor and kissed a lot of women, reporters, singers, AND fans!
So I'd say yes.
However, he said this in 2007: "I've not been a saint. I've had my lapses. / I've been in one of the biggest rock bands in the world for 25 years, and I'm not a saint, and I have not been a saint. / I don't have a mistress on the side or another family across town. You're never going to read that story about me. I have no regard for that whole lifestyle."

As far as you mentioned she doesn't care for his rock star life. I think you make the mistake of taking "rock star life" as his work. Jon is a songwriter and singer and also head of a business in music. I haven't read anything about that she doesn't care about these things.
