7 twerk-tastic photos from Miley's London concert

Just last month, Miley Cyrus was too sick to continue with her ongoing Bangerz tour. 

But now she's back in full tongue-lashing mode, as these photos from her concert at the O2 Arena in London on Tuesday night show. 

Tongues, twerking, wardrobe changes and even a wardrobe malfunction were some highlights from the show. 

Tongue-tastic

The ever-cheeky Cyrus, 21, appeared from an opening in her "mouth", or at least a visual representation of it which came as part of the stage design. She then took a trip on a slide that was clearly designed to look like her now famous tongue. 

Do the locomotion

Cyrus heading a choo-choo train line on stage was one of the more innocent things that happened during the sold out show. According to sources who spoke to The Daily Mail, Cyrus was "drinking water and spitting on the crowd", and asking the crowd to kiss people of the same sex.  

Miley and friends 

Dressed in a spangly leotard decorated with an oversized mouth and a tongue sticking out, she danced on stage with colourful friends ... 

... and friends with big ... assets. 

Twerk time

Not surprisingly, Cyrus one-upped her first outfit by changing into another leotard designed to look like it was made of dollar bills. 

She would go on to strike the same semi-twerk pose in different outfits, too, including this one below which had a, shall we say, "tropical" theme. 

But all that activity did result in a wardrobe malfunction at one point, and a member of her crew had to come up on stage to help her zip up her leotard.

It was too much for some, though. 

@Essex_Girlie tweeted: "One of my old work friends has walked out of the Miley Cyrus show at O2 cos she was being vile and disgusting....no shock there then (sic)".

But at least one superstar fan was thoroughly impressed. 

UK singer Lily Allen tweeted: 

@lilyallen: That was basically the best thing I've ever seen #BangerzTour #MileyCyrus

What do you think of Cyrus' on stage antics?
