Miley Cyrus is ready and rarin' to go when it comes to resuming her Bangerz Tour, which was postponed while the singer recovered from a severe allergic reaction that landed her in the hospital for two weeks. Before she kicked off the European leg of the tour in London last night (more on that below), Cyrus took the time to speak to reporters about her current health -- and to deny rumors about her health scare.

"I didn't have a drug overdose," Cyrus announced (via PEOPLE), referring to tabloid reports that claimed that was the reason she was in the hospital. "I took some sh––y antibiotics that a doctor gave me for a sinus infection and I had a reaction."

But now, as her dad Billy Ray Cyrus revealed during the iHeartRadio Music Awards, she is feeling in tip-top shape.

"I'm the poster child for good health," Cyrus explained, saying that she had been "connected to an IV for the last two weeks. I'm going to go off!"

Still, that doesn't mean that the 'Wrecking Ball' singer is out getting wrecked herself before each and every show -- in fact, she purposely abstains from any kind of mind-altering substance pre-show.

"I'm probably the only one on this tour who doesn't drink or smoke before a show, as I take this really seriously," she revealed. "It's almost like being an athlete being up here, because if someone was f––ed up, they definitely couldn't do my show."

"You have no idea how ready I am," she gushed before the show. "There is nothing I would rather not do than lay in a bed for two weeks. It was the most miserable two weeks of my life."

And indeed, she was ready. According to concertgoers' reports to UK's The Daily Mail, Cyrus was her usual raunchy self during her stop at the O2 arena in London last night, May 6.

"She got loads of people of the same sex to snog in the audience and put them on camera on a giant screen and made a speech about how we should all just 'be ourselves,'" one source said.

"She said she 'hopes we are all drunk and on loads of pills,' and at one point her dressers had to come on stage as her corset was undone," the concertgoer revealed.

Hmmm. While Miley Cyrus was proud to announce that she doesn't drink or do drugs before her show, we guess that doesn't stop her from encouraging fans to partake during the event.

PopCrushers + Smilers, what do you think of Miley's announcements?
