Look Back at Lady Gaga's Most Stunning Oscars Moments, Just Because She's Fabulous

In 2014, Gaga attended Elton John's exclusive Oscars party. She's pictured here along John and fellow attendees Donatella Versace and Heidi Klum.

Gaga walked the red carpet in 2015 wearing a gorgeously glittery Azzedine Alaia gown.

When Gaga was announced as the performer for 2015's tribute to Andrews and The Sound of Music's 50th anniversary, a lot of eyebrows were raised. But the moment she began singing with a classical, pure soprano, it was jaws that were dropping all across America.

Gaga was nominated for her first Oscar in 2016: best original song for "Til It Happens To You," a gut-wrenching anthem of survival featured in The Hunting Ground, a documentary about sexual assault on college campuses. While she ultimately lost to Spectre's Adele song "Writing's On The Wall," her performance of her song alongside a chorus of assault survivors was the broadcast's most emotional moment.

Gaga performed "Til It Happens To You" with a wide swath of college assault survivors singing at her side. The song is a heavy emotional experience, but the performance wasn't all about the weightiness: Gaga and the rest of the singers posed backstage for this photo.
