Miley Cyrus confessed at a London press conference that she did not have a drug overdose, CNN reports.

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

"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."

Miley Cyrus and Ricky Martin have been confirmed for a performance at the Billboard Music Awards 2014-the news has thousands of her Twitter and Instagram fans wondering if she will perform her Bangerz "Adore You" track at the show.

The "Adore You' singer started rumors she might be pregnant after being hospitalized on April 15 and canceling two concerts after being released, the Guardian Liberty Voice reports.

"If people did some research, they would come to realize that antibiotics are never prescribed in order to treat flu. Since flu is a viral infection, it is in no way affected by antibiotics. William Schaffner, chairman of the preventive medicine department at Medicine University in Nashville, says that taking antibiotic to treat flu is like taking a placebo," the website writes.

"If Miley really had flu, she should never have been prescribed with an antibiotic. According to that, the real question is, if Miley Cyrus is pregnant after all, since rumors have been spreading wide and she clearly did not share the truth about the real reason for her hospitalization."

Miley Cyrus' ex-fiancé Liam Hemsworth, who is rumored to be dating Nina Dobrev, was spotted vacationing in Venice Beach as the Bangerz tour star fights her antibiotic sickness in the hospital, Perez Hilton reports, leaving many wondering if the former couple is having a post-break up fight.

The "Adore You" singer made a mysterious Twitter post on Tuesday, filled with dozens of sad faces, just as it was revealed she might have to postpone upcoming Bangerz tour concerts again.
