Eva Longoria walked down the aisle on Saturday when she acted as bridesmaid at actor Mario Lopez's romantic beach wedding.

The Desperate Housewives beauty flew out to Mexico to watch her pal Lopez marry Courtney Mazza at Joe Francis' Casa Aramara villa in Punta Mita.

She took to her Twitter.com page to post photos of herself being zipped into her blue bridesmaid's dress, tweeting, "How many people does it take to zip up a dress? Apparently three! I can't breathe but the dress looks good!"

Lopez and Mazza had another special guest in their wedding party - their two-year-old daughter Gia was their flower girl, and donned a dress to match her mum's gown.

The traditional Catholic ceremony, attended by 150 guests, was taped for TV special Mario & Courtney's Wedding Fiesta, which will air in the U.S. on December 8.

It was not Lopez's first wedding - he was briefly married to actress Ali Landry in 2004. The union lasted less than a month.
