Jen, 39, has been a stowaway on current boy-toy John Mayer’s concert through Europe. The former Friends star was last seen in England heading out to dinner.

John recently talked about his dating life saying, “Instead of worrying about career damage, I’ve dated women!” (Which include Jennifer Love Hewitt, Cameron Diaz, Minka Kelly and Jessica Simpson, among others.)

The 30-year-old singer continued on by saying, “”All I’ve ever done was decided that I fancied somebody and said, ‘Would you like to go out and get a meal somewhere?’ And done so in a social setting, where other people can see you. And then maybe ‘Would you like to go have another meal?’ Maybe did that a few times.”
