A roller-coaster romantic history almost comes with the territory in Hollywood.
You're always meeting people, you never know who's around the corner, you're working with someone and the chemistry is off the charts... the temptations are endless. Some stars seem to have no intention of settling down, while others settle down every chance they get. Serial monogamy, no strings attached, boyfriend swapping with your squad, making it Instagram official—there are so many different ways to date. Even a lot of the couples who've been together for decades are on their second (or third) marriages. Sometimes it just takes multiple tries to get it right.
Regardless of how long the current relationship is, or how much time a star spent off the market, a lot of action—real and imagined—can be packed into one personal life. But has anyone had a love life quite like Tom Cruise?
