When we saw how hot Rihanna looked in her tuxedo at the Metropolitan Museum of Art Costume Institute gala on Monday night, we were reminded that she's certainly not the first chica to turn fancy menswear into an androgynous fashion statement. Here are some of our favorite ladies to go black-tie in the public eye:

Celine Dion: For the 1999 Academy Awards, the diva mixed things up by opting for white and then, apparently styled by by Kris Kross, she wore the jacket backwards! Let's not even get started on the hat.

Madonna: Of course, what Madonna wore at the 2005 VMAs was greatly overshadowed by the fact that she made out with Britney Spears and Christina Aguilera.

Everyone wanted to look amazing at this year's Oscars, and it was definitely a night for actresses to grace the red carpet in red or some shade of white. Some people did it right, while others left a lot to be desired.

Here are our picks for best and worst of Oscar fashion:

Best

Sarah Jessica Parker: The "Sex and the City" star loves to look like a ballerina, but she knows how to do it right and make sure she looks sexy.

Natalie Portman: Breaking the night's trend of red and white, she showed up in shocking pink. Portman looked sophisticated and fresh. Read more...

Given the false alarm that happened weeks ago, when someone told "Entertainment Tonight" that Brangelina's twins were born, it's no wonder everyone was skeptical about the announcement that the new Pitt-Jolies made their big debut Saturday night. But this time, we have confirmation from Dr. Michel Sussmann, who told The Associated Press that he delivered a boy and a girl via C-section at around 8 p.m. (France time) at La Fondation Lenval hospital in Nice, France.

The boy, Knox Leon, weighed just over 5 pounds, and the girl, Vivienne Marcheline, weighed 5 pounds. The actress, her twins and Brad Pitt "are doing marvelously well," Sussman told AP.

Earlier on Saturday, In Touch reported that she'd had her two girls at 6:45 and 7 p.m., according to "sources" at the hospital. Oops.

Of course, the world's hunger for photos of the couple's fifth and sixth children will soon be sated: French newspaper Nice Matin reported Sunday that they've already sold the rights to Knox and Vivienne's first photos to an unnamed U.S. publication. Proceeds will go to charity.

In the meantime, congrats at last to Angie, Brad, Maddox, Pax, Zahara and Shiloh!
