Liam Gallagher made a surprise appearance onstage at Lollapalooza Brasil last night as The Killers closed out the festival and when we say it was a surprise, we mean an actual surprise for everyone as Gallagher nearly gave Killers frontman Brandon Flowers a heart attack in the process.

The Killers were coming to the end of their headline set when Gallagher invaded the stage, albeit very gingerly, scaring the crap out of Flowers just as he was coming to the big finish of 'All These Things That I've Done', leading Flowers to exclaim "Fucking Liam Gallagher!" afterwards and a bit of mutual bowing before throwing in an impromptu cover of Oasis song 'Gas Panic' at the end.

It was an early noughties wet dream, basically.

And here's that moment in GIF form, just because we know you want it.
