Leave it to Mother Monster to make an entrance (or exit).
Just as Australian band Tame Impala were rounding up their performance at Sunday's FYF Festival with their hit song "New Person, Same Old Mistakes", Lady Gaga popped up on stage for a sing-a-long sesh.
If you're wondering what's the connection between the two, the band's lead singer Kevin Parker is one of the producers to her new song "Perfect Illusion."
We're sure it was a perfect end to the night (and no illusion) for fans who got to witness Gaga and Tame Impala perform together.
