Relationships are hard enough, but imagine the pressure of having your hook ups, "bumps" on the relationship road and breakups as fodder for the tabloids. More and more, it seems couples whose matters of the heart play out in the public eye are calling it quits and throwing in the towel on their relationships. Why is it so tough for these couples to stay together? Looking to shed light on the issue, VH1 will once again examine the complicated and often misunderstood world of high-profile relationships with Season 4 of "VH1 Couples Therapy." This season is more explosive and dramatic than ever as Dr. Jenn and her staff explore new relationship territory with the series’ first married lesbian couple, and one couple's relationship is so fragile it breaks just as therapy is getting underway. This season's couples include Taylor Armstrong from The Real Housewives of Beverly Hills and her partner John Bluher, Ghostface from The WuTang Clan and his partner Kelsey Byers, Jon Gosselin from Jon and Kate Plus 8 and his partner Liz Jannetta, Sada Bettencourt and Whitney Mixter from The Real L Word, and finally Farrah Abraham from MTVs 16 and Pregnant and Teen Mom.
