Miley Cyrus has been civil about her ex-fiance Liam Hemsworth since their September 2013 split, until she dissed him on stage this past weekend at London’s G-A-Y nightclub.

Before singing her Bangerz hit “Wrecking Ball,” Cyrus, 21, called it a “f—k you” to Hemsworth, never officially mentioning his name.

“I wrote this song after somebody broke my heart, and I just wanted to say 'f**k you,’” adding “I wanted to write a number one hit, something that would be on the radio. I wanted to make sure every time he turned on his radio, he would hear my song and will keep hearing it for the rest of his life,” Extra reports.

That wasn’t the only headline-making comment she made during her weekend performance. She’s also raising some eyebrows with a date rape drug joke she made. This comes as a surprise, because she’s a known LGBT advocate, Huffington Post reports.

“You know, everyone’s a little bit gay," she said. "Some of us just a little bit more than others... You know, it’s the truth. Everyone’s gay. All it takes is one cocktail. And if that doesn’t work, sprinkle something in their drink. That’s what I always do."
