Last month when she graced the cover of Elle Magazine, 21-year-old singer Miley Cyrus revealed that she was completely over her ex-fiance Liam Hemsworth.

"When I was with him or when I was on Disney, the thing that gave me the most anxiety was not knowing what to do with myself when Disney wasn't there to carry me anymore or if I didn't have him. And now I'm free of both of those things, and I'm fine. Like, I lay in bed at night by myself and I'm totally okay, and that's so much stronger than the person three years ago, who would have thought they would have died if they didn't have a boyfriend," she said.

But it seems that nowadays Miley Cyrus, who had once been nicknamed "Smiley Miley," has turned her smile upside down and is angry towards Hemsworth. At least, that's what it looks like.

During her penis-filled performance at London's G-A-Y club on Friday, Cyrus took a page from Kanye West's book and went on an emotional rant before singing her break-up song hit, "Wrecking Ball."

"And every time you get in your car, you're going to hear my f-king song on the f-king radio, you piece of sh-. That's right. And then I'm gonna take all my clothes off, I'm gonna sit on a big, giant dick -- sometimes two -- I'm gonna swing around, and then I'm gonna hold the record for the most-watched music video on Vevo. So then -- you know, you can tell a lot about a person -- I think you can tell how big their dick is by how much confidence they have usually, and if I was a dude I'd probably have a really big dick, 'cause I feel really good about myself now. So I'm gonna tell those motherf-kers that broke my heart, particularly one, to suck my fat dick and to enjoy hearing this song for the rest of your life. This song is called Wrecking Ball."

Uh... Bitter much?

This isn't the first bizarre tangent from Miley Cyrus. In addition to her Liam Hemsworth diss, Cyrus also joked about date rape at Friday's concert while performing fellatio on a plastic penis.

Wait, there's more.

Earlier in the week during her O2 arena stage performance in London, Cyrus told her fans how smoking weed got her laid more often.

Let's just blame Miley's bizarre antics on her being cooped up in the hospital for too long.
