Ariana Grande has been busy teasing the Mean Girls-inspired video for her No. 1 single "Thank U, Next," but before that arrives she's just launched her new YouTube Premium series, Dangerous Woman Diaries. The trailer for the series, which starts today, promises an intimate look at Grande during her Dangerous Woman tour as well as some footage of her performing.

The full series is now available to subscribers of YouTube Premium, but the first episode is also out now for free. Ariana has promised that a new episode will be available for free each week, with the second part free for all years in exactly a week from today.

The four part series features footage of her working on her most recent album Sweetener, and some footage from her One Love tribute concert in Manchester, UK. The first episode sees Ariana showing off Sweetener to some of her friends, joyfully testing some new material she had been working on at the time. Pharrell also shows up in the first episode, and it's likely that more of her high-profile collaborators will show up in subsequent entires in the series, too.
