Former Hannah Montana star Miley smokes, swears and dances dirty in the high school-themed promo, which also features rumoured new love interest Mike Will Made It, Wiz Khalifa and Juicy J.
And good news for fans of that MTV Video Music Awards performance - the foam finger is back!
The video stars with a typical high school prank in the headmaster's office while a scantily-clad, smoking Miley grafittis the mirrors in the girls' bathroom with red lipstick.
Miley - wearing a Michael Jordan-inspired skimpy outfit - later joins her crew at a pep rally, strutting her stuff on the basketball court, showing off her dance moves and even manages to enjoy some chill out time sitting on top of the hoop.
The 20-year-old also shows off her rapping skills in the video.
Miley is currently gearing up for the release of her new album Bangerz in October, which will feature the singles 'We Can't Stop' and 'Wrecking Ball'.
The video for 'Wrecking Ball', which features a totally naked Miley swinging around on, you guessed it, a wrecking ball, has clocked up 150 million views in just two weeks.
Let's see if smoking, rapping, most popular girl in the school Miley can do as well.
Watch the '23' video below - but be warned, it does contain swearing:
