Angelina Jolie and Billy Bob Thornton, Britney Spears and Jason Alexander and More Las Vegas Marriage Licenses Revealed

Did you know George Clooney was married before? No, really! Take a look.

Wondering how to celebrate this day of love with your special someone?

Instead of doing the usual fancy dinners and flowers like everyone else, how about going to Las Vegas and getting hitched?! Oh, too soon? OK, we're not trying to be a bad influence, but there are a number of big-named celebs that have tied the knot while in Sin City, and thanks to Ancestry.com, E! News has obtained some of their marriage licenses!

Here are four celeb couples that took the plunge while in Vegas...

1. Angelina Jolie and Billy Bob Thornton: This infamous and intense couple began their union in Sin City back in 2000. The ceremony happened on a Friday afternoon at the Little Church of the West on the Las Vegas Strip, and lasted all of 20 minutes, the chapel owner told E! News. What did the bride and groom wear? Well, they decided to keep it, um, simple...in jeans. However, their relationship ended in 2003.

2. Britney Spears and Jason Alexander: Who could forget the day they saw that the famous pop singer was suddenly married? And then in the blink of an eye—no longer married. In 2004, the childhood friends decided to tie the knot in a supersecret ceremony at Little White Wedding Chapel on the Strip while wearing jeans and a baseball cap. However, this wasn't exactly a lifelong, let alone a weeklong, marriage because just 55 hours later it was all over.

3. Demi Moore and Bruce Willis: This couple proved that not all Vegas weddings are just a little fling. The actors married Nov. 21, 1987 and had three daughters together: Rumer, Scout and Tallulah. And as much as we'd like to say they lived happily ever after, they didn't. Willis and Moore split in 2000, but the two are still very close and have supported each other through tough times, so in Hollywood terms, that's pretty close.

4. George Clooney and Talia Balsam: Yep, you better believe it. This famed Hollywood bachelor wasn't always a bachelor! The actor got hitched in Las Vegas to the actress way back in 1989. They lasted for three years before calling it quits, and Clooney became the epitome of the unattainable man. Balsalm, however, went on to be happily married to Mad Men's Jon Slattery, who just plays an unattainable man on TV.
