engaged costume party beso

Hmm, did the engaged couple get their eras wrong?

Actress Eva Longoria turns 36 on March 15th, but last night she celebrated early with a costume birthday party at Beso in Hollywood...

Kim K. Tweeted some pics from the evening - check 'em out below!

Along with the caption, "Celebrating the glamorous @EvaLongoria's bday 1920's style!"

But it looks like Nick Lachey went in 70s clothes and ladylove Vanessa Minnillo in 80s? Take a look below the cut of Kim K. with Heidi Klum, who was also at the party... in a 20s-themed costume.
