Miley Cyrus shoots down overdose rumors: 'I'm the poster child for good health'

Miley Cyrus returned to her Bangerz tour Tuesday night at the O2 Arena in central London after a health crisis caused her to missed several dates.

A recent health crisis sparked by a reaction to a prescribed medication resulted in more than just a hospital stay for Miley Cyrus. It set off rumors that the pop star had a very different sort of drug problem.

"I didn't have a drug overdose," Cyrus told reporters at a press conference at London's O2 Arena Tuesday. "I took some (expletive) antibiotics that a doctor gave me for a sinus infection, and I had a reaction."

The ailment caused the singer to miss several dates on her Bangerz tour, but she insisted that she feels "better than ever" now.

"I'm the poster child for good health," she said, adding that her current care regimen includes lavender, honey and "a crazy vitamin rush."

Thanks to all of that, and presumably to the care she received during her hospital stay, Cyrus was ready to take the stage again Tuesday night.

"You have no idea how ready I am," she said ahead of her O2 performance. "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."

According to the singer, there's no need for her fans to worry now.

"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 said. "It's almost like being an athlete being up here, because if someone was (messed up), they definitely couldn't do my show."
