When they first started dating, John Mayer and Katy Perry split frequently. She would find out about some other person he was having sex with or some other fetish he just had to try with Katy or had previously tried which made Katy squeamish. With most of those finally discussed and worked through you would think the couple would be able to get through almost anything because, lets face it, John Mayer's list is way longer than most people. What their relationship didn't foresee is Miley Cyrus. Miley is two for two this week in splitting up people who have had the misfortune of rubbing against her. She twerked her way to a Robin Thicke split and kissed her way to a Katy Perry split. How many other relationships have suffered along the way that we don't know anything about. Is it any wonder that her parents are constantly splitting? Miley kisses one hello and boom the marriage is over. Her brother? His relationship starts and stops more than Lindsay Lohan casing a jewelry store. Her older sister? I think she gave up on a relationship after Miley kept hugging her all the time. Those poor little people on her tour are probably relationship cursed at this point. The only cure is a year off from Miley. Once she touches you it wears off after about a year.
