She removed the glasses to reveal tears on her face as she sang, with rumours recently surfacing that she has split from boyfriend Taylor Kinney.

But Gaga's tearful performance wasn't the first emotional showing in an increasingly bizarre broadcast.
In the show's most awkward moment, hosts Jason Schwartzman and Reggie Watts carried crying babies through the crowd and tried to interview Macklemore and Lewis as they presented them with the Breakthrough award.
Meanwhile, Hudgens and actor Michael Shannon took part in a music video skit which ended up with a 'fan' invading the stage and getting Vanessa in a headlock.
The star ended up sprawled on the floor.

Famed director Spike Jonze directed live videos with Eminem, Gaga, M.I.A. and rapper Earl Sweatshirt.
Eminem was named artist of the year before performing a word-perfect version of his new lung-busting tour de force Rap God, filmed in black and white.

Actress Gina Gerwig kicked the awards off as the protagonist of a live video of Arcade Fire's Afterlife, directed by Jonze.

Gerwig appeared to break up with her boyfriend, then expresses the emotions she's feeling in an interpretive dance that moved from apartment to forest to soundstage with a little visual trickery.
A short while later Schwartzman and Watts admitted they would be working the 90-minute show without a script - with just notecards standing between them and awkward pauses and brief technical difficulties.
'This is all about anything happening,' Schwartzman said.

Arcade Fire frontman Win Butler stepped into the shot to take photos with his iPhone, the show's hosts ran through the crowd a few times, climbed a ladder, participated in face-painting, performing not one but two improvised songs.
Earl Sweatshirt and fellow rapper Tyler, the Creator, performed their song Sasquatch in the midst of a mosh pit, using hand-held cameras to relay the frenetic experience while Avicii played the dumb hot guy part in a short film that concluded with a blood-spattered faked double suicide.
And Butler made a return to the stage when he jokingly interrupted as a group of Swift fans accepted her YouTube Phenomenon award for I Knew You Were Trouble.

He recreated the infamous moment when Kanye West rushed the stage during Swift's win at the MTV Video Music Awards.
'Not Taylor Swift,' Butler said. 'I'm gonna let you finish. Not Taylor Swift. The YouTube phenomenon of the year was definitely the Harlem Shake.
'I don't know. No disrespect, but everybody knows that if you've ever been on YouTube, so whatever.' He then dropped the mic and walked off stage.
