The Wrecking Ball singer will kick off the UK leg of the tour at London's O2 arena tonight - and told the world of her excitement in no uncertain terms in a series of expletive-filled posts on Twitter.
Over the weekend she tweeted: "so f****** xxxited to get back on touuuuuuuurrrrrr", followed by "turndownforwhatLONDON" and "imbackmaf***a #f***yeahLondon".
She also posted a number of photos featuring her trademark pose with her tongue out, and a video on Instagram dancing on a couch and twerking with a friend.
The 21-year-old postponed her US tour last month but has begun the European leg and and will resume performances in America on August 1 in New York
Her representative said the singer suffered from a sinus infection during her Bangerz tour and had "an extreme allergic reaction" to the antibiotic cephalexin on April 15, leading to the cancellation of several shows.
She is due to play Glasgow's Hydro on Monday, May 12.
