More details have been emerging about Miley Cyrus' secret gig at G-A-Y on Friday night - and it seems the pop star was very forthright about ex-BF Liam Hemsworth.

The 21-year-old singer bought a taste of her current Bangerz tour to the famous London club and those lucky enough to get in have reported that she gave her old flame a mouthful as she introduced her global hit Wrecking Ball.

She told the crowd: "I wrote this song after somebody broke my heart, and I just wanted to say 'f*** you'.

"I wanted to write a No 1 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."

According to The Mirror, Miley also revealed that she was "seriously f***ing drunk" on vodka and Sprite and had "barely slept for 24 hours".

Miley has only just returned to action after a serious allergic reaction laid her low last month.
