Just two days after leaving rehab at the Betty Ford Center, a refreshed and healthier looking Gerard Butler hit up the Vanity Fair Oscar Party in L.A. on Sunday.

Butler spent three weeks in treatment after realizing he was relying too heavily on prescription medication.

TMZ broke the story ... Butler began using pain meds to deal with the pain caused by the intense physical training regimen to get in shape for "300" ... and the problem became exacerbated after he injured himself in a surfing accident while filming "Of Men and Mavericks" back in December.

It's the Oscars, time to honor the best in this year's films and, more importantly, critique what everyone wore!

Check out the good, the bad and the ugly.

Sacha Baron Cohen took shameless promotion to a whole other level on the red carpet of the Oscars tonight -- not only did he show up dressed as his character from the upcoming movie "The Dictator" ... but he spilled an urn filled with fake ashes of Kim Jong Il all over Ryan Seacrest on live television.

Props to Seacrest though ... as he always does, Ryan took the whole thing in stride. 

Like the king and queen of the Hollywood prom, Brad Pitt and Angelina Jolie -- and her legs -- were among the last to arrive to the Academy Awards on Sunday.

We are not worthy.

Gwyneth Paltrow showed up to the Academy Awards wearing what looks like the remains of Celine Dion's infamous backward white tuxedo from the '99 Oscars.

We're just sayin'.

Looking like twinsies, "Scary Movie" queen Anna Faris and "Bridesmaids" babe Rose Byrne both wore severe bangs and shimmery black gowns to the Oscars.

Question is ...

Oscar nominated for his role in "Moneyball," Jonah Hill wears a little black tux to the Academy Awards.

He's becoming a really big star again.

Oscar nominee George Clooney arrives to the Academy Awards with his gorgeous former wrestler girlfriend Stacy Keibler.

Whether he wins or loses, he's taking home a statue.

For some reason, former "Caroline in the City" star Lea Thompson was one of the first to arrive at the Oscars today.

Perhaps she is getting an honorary Academy Award for her stellar work in "Howard the Duck."

Whatever the reason, it's some kind of wonderful.

With the 84th Annual Academy Awards just hours away, take a mystical trip back in time and check out the good, the bad and the ugly from last year's fashion fiascoes!

**Be sure to check back this afternoon to see all of this year's Oscars action!**

Wearing a plunging low cut orange number, Best Actress Oscar nominee Viola Davis showed off some of her other God-given talents at the NAACP Image Awards in L.A. this weekend.

The buxom 46-year-old definitely doesn't need any help in this area.
