Beware of the serial dater: John Mayer
Just because they're cute (and, in John Mayer's case, happen to write swoon-worthy songs) doesn't mean they're acceptable Valentines. Just check out Mayer's dating history!
T-Swift doesn't exactly have the greatest track record when it comes to dating, but neither does John. This relationship lasted three months and inspired at least one song.
John referred to Jessica as "sexual napalm" (he meant it nicely) and said she was like crack cocaine to him — completely addicting. Still, their relationship ran its course after 10 months.
John and Jen lasted for about 11 months. When they first broke up, John dished some pretty rough criticism of her. Later, though, he said he still isn't quite over her.
Jen Love Hewitt
We're still not entirely certain how this happened, but in 2002, Jennifer Love Hewitt and John Mayer dated and seemed quite happy. All good things must come to an end, though.
Despite rumors that John Mayer dumped Minka so he could hook up with Jennifer Aniston, Mayer insists that he remains good friends with the former Friday Night Lights star.
Katy is John's newest high-profile girlfriend. Fresh from her divorce from Russell Brand, Katy and John have been everywhere lately. We love Katy and we love John, but we're not fans of this.
