They’re music royalty with coolness oozing out of their perfect pores but not even 13-years of marriage and three kids could save Gwen Stefani and Gavin Rossdale from ending it.

In Hollywood, it seems all good McDreamies must come to an end… even Patrick and Jillian Dempsey’s 15 year marriage. “It is with careful consideration and mutual respect that we have decided to end our marriage. Our primary concern remains the wellbeing of our children, and we ask with profound gratitude that you respect our family’s privacy at this very sensitive time,” the pair said in January.

Brian McFadden and Vogue Williams revealed the end of their marriage in a very modern way in June this year, thorough simultaneous Twitter messages of course! “It is with sadness that [we] have made the tough decision to go our separate ways. We will always care greatly about each other all the very best for the future,” the statement said. The duo tied the knot in a lavish ceremony in Tuscany in 2012 and had often talked about starting a family.

RIP Bennifer 2.0, you broke our hearts after announcing your divorce just one day after your 10th wedding anniversary. Please get back together so we can believe in love again?

But Cody Simpson,18, and Gigi Hadid, 20, just weren’t meant to be and put the brakes on their relationship in May. “It’s tough because like, you know, I have a best friend in Gigi and like, we’ve been together and we’ve been broken up for certain reasons and we’ve been back together and we’ve been broken up,” the Aussie singer eloquently explained during a chat on The Bump recently.

If ever there was a reality TV love story for the ages, it was Kourtney Kardashian and Scott Disick’s epic saga.
