Ariana Grande is no more the sweet girl we once knew. The "Problem" singer is trying hard to break her bubbly image. At the Bambi Awards in Berlin on Thursday night, she wore a risque outfit, revealing her derriere. The singer wore a black leather leotard, a sheer skirt and a pair of boots as she belted out some breath-taking numbers. She flaunted her assets quite a few times as she showed off her dance moves while singing "Break Free" and "All My Love."

The 21-year-old singer also won the award in the Best Newcomer category.

"Ariana Grande is a young singer with a powerful voice who knows how to combine pop, soul, hip-hop and electronic music to form an irresistible dance sound. Her hits set new records on iTunes, her concerts sell out and she has millions of fans on Facebook, Twitter and Instagram. Her unmistakeable voice and unusual range spanning five octaves make her one of the exceptional talents of our time," said the Bambi Panel for picking up Grande for the award, according to Daily Mail reports.

Grande's musical career has been going from strength to strength. She has been compared to Maria Carey on several occasions. As her music is evolving, she is also taking serious steps towards her dressing style. On 9 November, she was seen wearing a cut out Michael Kors gown.

She kept her hair open and her make-up featured red lips and heavy black eyeliner. She wore no accessories. Her new style was definitely a departure from the girly image she has been carrying so far. On personal front, Grande is dating Big Sean. The two have been friends for a long time and are now said to be dating. Though they have not confirmed that they are in a relationship, they have expressed their liking for each other in various interviews.

In the past, Grande has dated The Wanted's Nathan Sykes and Jai Brooks. Big Sean has dated Naya Rivera. The duo was engaged but they called it quits just before walking the aisle.
