With her "Bangerz" world tour around the corner, Miley Cyrus is leaving no stones unturned to make it the best of her road trip ever. The 21-year-old songstress has posted some really provocative pictures of her rehearsing for her upcoming "Bangerz" tour on her Instagram page. The pictures give Miley's fans a sneak peak of what she has in store for everyone and looking at it guarantees lots of fun and excitement apart from short dresses and blonde wigs.

One picture shows Miley's pert posterior (her bums) jutting out of a very tight one piece dress. Miley is seen spanking a back-up dancer's behind and faces her back towards the camera. Miley seems to rehearsing on one of her twerking dance move. See picture here.

On Monday, the "Adore You" singer also posted another picture which shows her wearing a red, white and blue leotard dress and a blonde wig. She is seen dancing with three other dancers in similar clothes. See here.

The "Wrecking Ball" songstress will kick off her "Bangerz" tour on Valentine's Day in Vancouver, Canada. The Nashville born singer will then tour in 38 cities in North America before hitting the road in Europe on May 2 for more than 21 days.

The singer is quite upbeat about her road trip and told E! Online that she purposely chose Valentine's Day to kick off her tour so that she does not have to be "depressed" on that day. Miley is now single after she broke off with "Hunger Games" actor Liam Hemsworth in 2013.

Miley also told Fuse News recently that contrary to popular beliefs her upcoming tour will be beneficial for children. "Even though parents probably won't think this, I think my show is educational for kids because of the art they're going to be exposed to that most people don't know about," Miley told Fuse News.

"I want to make all my content look high end, something that you would see on Madonna's tour, but then just make it feel a lot more young," Miley added.
