John Mayer – Singer – 43

With his stunning voice and rugged albeit boyish looks, John Mayer has been a heartthrob since he burst into the music scene in 2002. The famed singer has had his fair share of failed relationships and has been associated romantically with Katy Perry and Taylor Swift, though all those unions eventually dissolved.

We doubt he would have trouble getting himself back into the dating pool if he wanted to, Mayer wouldn’t be short of suitors. As successful as he is, we bet John’s busy making more music and enjoying bachelorhood too much to be thinking about settling down.
