While celebrities dating other celebrities is about as common as it gets in the universe known as Hollywood, it's still a bit of a rarity when two full-blown supernovas collide.
But that is what has happened with Jennifer Lopez and Alex Rodriguez—she the singing, dancing, acting and business multi-threat known simply as J.Lo, and he a World Series-winning, three-time American League MVP who at one time was the highest-paid player in baseball who also has himself a jaunty nickname in A-Rod.
Seriously, where have these two been hiding from each other? Aside from separate yachts?
They're both native New Yorkers, both from humble beginnings, both parents of two. They both bring to the table inimitable talents, international fame, wealth beyond belief—and very public relationship histories that are as storied, twisty-turny and tabloid-friendly as they come.
Interestingly, though they were almost never on the same page (albeit apart and while in other relationships), they've experienced similarly wavering levels of devotion and commitment over the years, depending on the situation; they were just famous ships in the night, one going through this while the other was going through that, and so on.
