So who is the latest lucky one to be sharing a smooch with the 21-year-old pop star? That would be Cyrus' new label mate, rapper Brooke Candy.
Candy added a simple caption to the sultry snapshot : "YUM."
It's unclear when the steamy photograph was taken, but the platinum blond ladies are clearly enjoying each other's company.
As for Cyrus' kiss with Perry, the singing sensation was performing "Adore You" and in the middle of the tune, she bent down to give the "Dark Horse" crooner a smooch.
"I just kissed a girl and I really liked it a lot," Cyrus declared after the pals' spontaneous moment, which was captured in this fan's Instagram video. And the blond beauty also made a perfect reference to Perry's smash hit from 2008.
