Miley Cyrus Rejects Drug Claims At London Gig

Miley Cyrus has rejected claims she took a drug overdose, as her UK tour got off to a provocative and controversial start.

The Wrecking Ball singer boasted about her fine physical health after a sinus infection and an allergic reaction to an antibiotic forced her to cancel shows in the US.

At an energetic press conference before the first show at The O2 in London, the 21-year-old said she was "the poster child for good health" and promised to "f*** this place up".

Cyrus set the tone for her show when she arrived on stage by descending down a long, pink slide resembling her tongue, which was protruding from a giant image of her face.

"Hello, mother f*****s! I'm not going down without a motherf*****g fight!" she yelled, wearing a silver one-piece with a stick-on pair of lips.

Cyrus, who went sightseeing before the concert, then launched into the tour's opening song, SMS (Bangerz), accompanied by a pantomime horse, a dwarf and a troupe of dancers.

Many in the predominantly young crowd mouthed along to her songs but some parents were left unimpressed with Cyrus' antics.

She slapped herself in an intimate area, simulated foreplay on a bed with a dancer and showered fans in the first few rows with gargled water.

Cyrus also reportedly discussed drugs during the show.

A father who went with his 15-year-old son said: "It would be different if it was a good show. But it's not even a good show."

"She's lost the plot," another said.

The set included a peculiar interlude featuring a black and white film of an almost-naked Cyrus pulling faces set to British band Alt-J's Fitzpleasure.

She then returned to a satellite stage and took a selfie.

Cyrus then tried her hand at a number of covers, putting her own stamp on songs from the Arctic Monkeys, Bob Dylan and her godmother, Dolly Parton.

The finale featured Cyrus soaring over the stage attached to "the biggest wiener in London" - a reference to an inflatable hot dog.

The encore included Cyrus' biggest hits, UK chart-toppers We Can't Stop and Wrecking Ball, followed by Party in the USA.

For her closing number, she altered the lyrics to reflect her location and wore a Union flag one-piece.

Cyrus' next gig is in Leeds on Saturday, followed by performances in Glasgow, Manchester and Birmingham.
