Miley Cyrus: I didn't overdose on drugs

There was much excitement when Miley Cyrus launched her "Bangerz" tour in Vancouver, British Columbia, in February, but since then the controversial singer has been beset by woes including ending up in the hospital with "a severe allergic reaction to antibiotics." Here are a few other issues that have cropped up along the way.

Katy Perry and Cyrus got in some smooching action during the latter's Los Angeles concert in February. Cyrus tweeted the lip lock, though the pair later got into a beef about the smooch when Perry questioned Cyrus' tongue hygiene during a radio interview in March. They later made up -- via Twitter, of course.

In April 2014, a "Bangerz" tour bus caught fire, according to Cyrus' younger sister, Noah, who chronicled the incident on Twitter.

Tragedy struck in early April with the death of the singer's favorite pooch, Floyd. Cyrus tweeted to her Boston fans in advance of her concert there that she was "beyond miserable." The gift of a new dog from her mother apparently did little to console her, as Cyrus later tweeted that she gave the new dog away to a friend.

On April 15, Cyrus was hospitalized for a "severe" allergic reaction to antibiotics reportedly taken for a bout with the flu and had to cancel some dates. "Kansas I promise Im as (heartbroken) as you are," the singer wrote. "I wanted so badly 2 b there 2night. Not being with yall makes me feel s**ttier than I already do."

(CNN) -- Miley Cyrus may be well-known for some wild antics, but she insists taking drugs is not one of them.

According to People, the singer refuted rumors that her recent illness was anything other than the reported bad reaction to medicine. It led to the rescheduling of some dates for her "Bangerz" tour.

Cyrus insisted she is "the poster child for good health" while speaking Tuesday during a press conference at London's O2 Arena in anticipation of her rebooted European tour.

"I didn't have a drug overdose," she said. "I took some s****y antibiotics that a doctor gave me for a sinus infection and I had a reaction."

Cyrus fell ill in April while on tour and was hospitalized for an "extreme allergic reaction." The illness also caused her to delay the start of her European tour.

The former "Hannah Montana" star now says she is on the mend, thanks in part to vitamins and honey. She said she was happy to be past "the most miserable two weeks of my life."

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