These filmmakers famously did not get along during the making of their movies.

Most of us don't get to choose our names, but celebrities do -- and when they start out with a snark-worthy or tongue-twisting real name, it makes the decision to abandon it even easier. With that in mind, here are five stars with given names that probably wouldn't have gone up in lights, and the stories behind the stage names they chose instead...

Experts say the younger you are when you get married, the more likely your marriage is to end in divorce. Still, that hasn't stopped plenty of stars from taking the plunge before their 20th birthdays -- and while most of these unions predictably didn't last, a few did stand the test of time...

So rather than fight the elements, beachy bedhead waves allow celebs to be artfully disheveled and messy on purpose. The "I just woke up" look can be styled in a variety of ways, like Olivia Wilde's defined semi-curls or Selena Gomez's tumbling tendrils.

Today (July 22), some celebs talked about the upcoming birth of the royal baby (who finally arrived today), some people spoke in memory of character actor Dennis Farina, and Olivia Wilde somehow managed to do both.

Want to lose weight and have fun doing it? According to comedian Jason Sudeikis, it's easy. All you have to do is be in a relationship with Olivia Wilde, spend a bunch of time sexing her up, and the pounds will just melt away. How's that for an infomercial?

Today (July 16) was a day of stars sharing many secrets of the universe. Like secrets about how ads made them crazy, or secrets about what screenwriters are really thinking. They know the secrets to happiness and how to get cheese balls from Honey Boo Boo. Listen to the tweets of the stars. You could learn something.

Being a bridesmaid is tough business. It's expensive and you often end up stuck in a dress of the bride's taste and choosing -- one you normally wouldn't have selected for yourself. You wear it once and it's exiled to a hanger -- maybe even a wire one at that -- in the back of your closet for the rest of its damned life. Unless, of course, you're set to be one of actress Olivia Wilde's bridesmaid

Today (July 3) was filled with randomness in the world of celebrity Twitter. Some were stuck on games, marred their own faces, pretended to work at K-mart, gave strangers money and handed out wisdom for our weekend. All were amusing and appreciated.

Today (June 25) the celebs made wishes, screwed up at the drive-thru, skateboarded and lusted after Jan Brady -- among other things.

'Saturday Night Live' comedian Jason Sudeikis and his lovely fiancee Olivia Wilde brought the yuks to Kansas City, Missouri to raise money for the cancer support group Gilda's Club, named after the late legendary 'SNL' comedienne Gilda Radner.

Our Best + Worst Dressed this week finds Taylor Swift occupying two spots and mommy-to-be Halle Berry on the right side of maternity dressing. There are also some familiar faces who keep repeating their positions on this list.

It's time for this week's Best and Worst Dressed, with actress Kirsten Dunst getting the LBD right thanks to smart makeup and accessorizing, the pregnant Fergie getting the LBD all wrong with her Stevie Nicks-like layers -- and more.

It wasn't long ago that Olivia Wilde, caring person that she is, used Twitter to offer some advice to young Justin Bieber, who recently walked around London sans shirt like a tiny Canadian Matthew McConaughey. Afterwards, she took a whole lotta heat from the world's Beliebers -- and on Tuesday, March 12, she hilariously told Jay Leno all about it.

Olivia Wilde bravely went where many dare not dwell (except for Patrick Carney, who seems to enjoy igniting the ire of teenage fan bases) by insulting Justin Bieber on the interwebs.

Congrats to 'SNL' actor Jason Sudeikis and former 'House' actress and unfairly beautiful Olivia Wilde are engaged. Gentlemen, this is further proof: The funny guy always gets the hot girl in the end.
