Just like many regular couples, relationships in Hollywood are anything but smooth sailing (just ask Tom Cruise and Katie Holmes). From busy schedules, bicoastal lives and the never-ending rumor mill, it seems it's hard to keep any relationship off the rocks in Tinseltown.
But not all breakups are forever.
Most recently, on-again, off-again couple Elisabetta Canalis -- who once dated George Clooney -- and "Jackass" star Steve-O were spotted together in West Hollywood last week, just a few months after calling it quits. The couple first started dating in early 2012, but parted ways a few months later.
If Canalis and Steve-O are indeed rekindling their romance, they certainly won't be the first celebrity couple to do so.
