Dirty Dancing at the ALMA Awards!

Eva Longoria - with just one month to go until her big wedding to Tony Parker - wowed the crowd at the 2007 ALMA Awards celebrating Latinos in the arts.

But it wasn't just her stunning beauty that was dropping jaws - it was her costume changes!

After arriving on the red carpet in a stunning Gustavo Cadile gown, she took the stage in a whopping 14 different outfits.

But it was the opening number with "Extra's" own Mario Lopez that got the most buzz!

The "Dancing with the Stars" hunk swept Eva off her feet - literally! - to a cheering crowd.

"I loved it!" said Rodrigo Santoro, the sexy Latino from "The 300" and "Lost."

But the night's biggest surprise? An unexpected appearance by a very expectant Salma Hayek!

"Salma being here was really great for us," said Eva.

When George Lopez picked up a special award for changing the face of television, he gushed, "It's a beautiful night!"

And Beyonce rocked the house - singing in Spanish, live via satellite from Madrid!

Then, once it was all over, "Extra" was the only show invited to Tu Cuidad Magazine's official ALMA after-party, where we got close to Eva and the gang.

Eva told us that now that her work is done with the awards - it's time for a little R and R!

"I am finally on vacation!" she said.
