Love is messy, to say the least, and the romantic entanglements of celebrities are no exception. Here are five famous couples who know all too well the feeling of changing their Facebook status to "It's complicated."
1. Chris Brown & Rihanna
Not even a restraining order could keep these two apart. Everyone thought that the very public domestic violence Rihanna endured at the hands of Chris in 2008 would end the relationship—and it did, for a while. A year later though, Chris and Riri were back together. Until they weren't. Rumors of the two getting back together have swirled since 2013, and continue to this day.
2. Chris Brown & Karrueche Tran
During the four years they dated, Chris and Karrueche had more than their fair share of drama. Highlights: Chris publicly claiming that Karrueche cheated on him with Drake while he was in jail, Karrueche taking to Twitter to say she couldn't take any "baby drama" (Chris has been in and out of court with baby mama Nia Guzman), and of course, the fact that Chris's relationship with Rihanna and Karrueche overlapped multiple times. So messy. The two are currently still on the outs.
3. Scott Disick/Kourtney Kardashian
If your relationship is making Kyga—a relationship we believe is fundamentally unhealthy—look stable, then you're in trouble. Scott and Kourtney have been on-again, off-again since basically the beginning of their relationship in 2006. They separated again earlier this summer, and Scott recently made headlines for dating an 18-year-old model. Chances are, they'll be on the outs for a while, which is a shame because Kourtney and Scott's one-liners are literally the only reason to watch Keeping Up With The Kardashians.
4. Justin Bieber/Selena Gomez
"The heart wants what it wants," and apparently what Selena's heart wants is Justin Bieber. Remember when, way back in 2010, Selena told Ellen that Justin was like her little brother? If only it had stayed that way. The two officially started dating in 2011, and it was a whirlwind from there. It was a match made in tween pop star heaven—until they split the following year, and then continued to break up and get back together over and over again (though almost always unofficially).
5. Megan Fox and Brian Austin Green
Megan Fox and Brian Austin Green first got together in 2004. It was a May-December relationship (she was 18, he was 30). They got engaged in 2006 and then split in 2009, only to get married a year later. They welcomed their first child into their lives in 2012, and had a second two years later. Megan filed for divorce in August of this year, and Brian apparently wants spousal support, claiming that, because of a car accident he and Fox were involved in last year, he has an ongoing case of vertigo that renders him unable to work.
