Lady Gaga Gets Emotional Performing 'Shallow' During Opening Night of Las Vegas Residency
Giant Robots & Wild Wigs: Inside Opening Night of Gaga's Vegas Residency

Fans go "off the deep end" as Gaga sings the song live for the first time.

Lady Gaga had to pause her performance of "Shallow" during opening night of her new Las Vegas residency on Friday, after getting overcome with emotion.

The singer kicked off her two year-long "Enigma" show at the Park Theater at Park MGM last night, debuting an electric space-themed concert filled with giant robots, wild wigs and more over-the-top theatrics we've all come to expect from the performer.

She rolled through her greatest hits, including "Born This Way," "Just Dance," and "Bad Romance," performed a cover of David Bowie's "I'm Afraid of Americans" and shook her Little Monsters to their cores when she sang the breakout single from "A Star Is Born," "Shallow."

The 2019 Golden Globe and Grammy-nominated song came during the encore for the evening, as Gaga sang it live for the very first time. It was clearly an emotional moment, as she teared up after walking out to the track's signature guitar intro.

"For a really long time, I felt so misunderstood," she told the crowd. "They thought the way I dressed, the way I talked, attitude, they thought it was shallow, but this shit is deep as f--k."

"I love you so much," she continued. "I'm so proud to be your star, but the truth is, you gave birth to me."

Gaga walked to the piano and began the ballad by singing Bradley Cooper's part. The Grammy winner's voice cracked when performing the first verse, pausing for a moment before pulling herself together to finish the song.

As fans continued to post footage from the concert all night -- something she encouraged at the top of the show -- those at home took to Twitter to give Gaga all the "Applause" she deserved.

"Enigma" runs through November 9, 2019, at Park Theater at Park MGM Las Vegas. See the full setlist below.
