2. The White Stripes Jack and Meg White kept their relationship mysterious and vague at best. At first they put on the act of being brother and sister, but it was later revealed that they had been married and divorced prior to their band together ever even achieving any success.

For a divorced couple, they certainly didn't seem to have any hard feelings over it. That is, until Meg White remarried in 2009. The band quickly dissolved soon thereafter, finally issuing a statement that they were finished in 2011. Then Jack White released a very bizarre solo album called Blunderbuss that certainly sounded like a pained breakup record. Who even knows with that pair?

1. Fleetwood Mac The most famous couple to break up and still make their business together work is Fleetwood Mac, and as they prove, it's not easy. Though they never married, Stevie Nicks and Lindsey Buckingham's relationship lasted from the late '60s on into Fleetwood Mac's great mid-70s success, but by the time of their hit 1977 record Rumours, they were done. Likewise, John and Christine McVie were together from 1969 until right after Rumours, when they divorced.

Somehow, the band stuck around through both breaks, even though the relationships remain tenuous to this day. In fact, even in March, Buckingham and Nicks were involved in a back-and-forth row via Rolling Stone. Yet a new EP from the band recently dropped, titled simply Extended Play, and Fleetwood Mac is set to hit Houston's Toyota Center tomorrow night.
