The 27-year-old pop star jetted to Cabo San Lucas, Mexico, last week for the nuptials of former schoolmate and BFF Bo O'Connor, where Gaga was the apparent maid of honour in a bridal party of six on Saturday.

In a dusty pink halter gown, the songstress rocked platinum blond hair and simple makeup. An oversized flower in her tresses aside, there wasn't a trace of the larger-than-life outerwear we're used to from the diva.

It's nice to see a makeunder for a change. And besides, weddings are about the bride and groom.

The weekend service gave way to a sunset cocktail hour. While we didn't spot Gaga's on-and-off actor beau, Taylor Kinney, Gaga seemed content in toasting her pal's happiness.

Mother Monster has spent the past several months recovering from hip surgery. Her fourth studio album, "Artpop," is scheduled for release later this year. She'll also make her feature film debut on July 31 when "Machete Kills" hits theatres.
