Hollywood is famous for a lot of things — but cultivating healthy, long-lasting relationships isn't one of them. When celebs tie the knot, there's always an underlying sense that the marriage isn't going to last. Even the unions that seem most unshakable can go south. We're still reeling from the end of Jen and Brad, not to mention Bennifer, take two.

Of course, there's no shame in ending a marriage that has run its course, but not all celebrity marriages are doomed. Some superstar couples have managed to make it work for 15, 30, or even 45 years and counting. And we're not just talking about the same duos you always hear about (Will and Jada! Kevin Bacon and Kyra Sedgwick! Tom Hanks and Rita Wilson!). There are plenty of other A-listers who've been hitched for WAY longer than you might realize.

Click through for our list of 15 famous couples who said "I do" — and meant it. And the next time you're questioning whether true love is real, just remember: For every Gwen and Gavin, there's a Julia Louis-Dreyfus and Brad Hall.
