Ariana Grande goes sci-fi with her MTV EMAs performance

Say what you will about Ariana Grande, the lady knows how to make an entrance.

At the 2014 MTV Europe Music Awards – which took place in Glasgow, Scotland and featured predominantly American artists – Grande slowly emerged from under the stage in front of a psychedelic black and white swirling, strobing background, and kicked off the performance with her song "Problem."

In a rare move, the singer wore her hair down – instead of her signature pony tail – but then wore her traditional pseudo-futuristic ivory corset/swimsuit/bustier combo that showed off her impressive legs.

She sang a few bars of "Problem" before getting safety-belted into a glass-encased bubble chair on wires that flew her over the audience while she sang "Break Free."

Her Wizard Of Oz-like bubble then took her to a different stage decked out with a whole lot of back-up dances, some giant crystals, and mini-volcanoes shooting out dense fog. It was like she borrowed the set from the classic kids' show 'Land Of The Lost.'

The whole piece felt like a sci-fi movie from the 1970s, but in a good way. You have to hand it to the 21-year old star: She does know a thing or two about spectacle.

Despite her fans and success, Ariana has been battling rumors that she's a "diva" and that she's hard to work with. Check out the video below to hear how the "Problem" singer responds to these claims.
