In August 2014, producer and engineer Ian Cross, who worked on her last three studio albums, confirmed to
Barefoot Sound that he was working on Jackson's new album, stating they worked in recording studios in Qatar, Paris and Middle East. After his declarations, Jackson herself responded to the rumor, neither confirming nor denying the works: "If there is a new project, you'll hear it from my lips", she tweeted. On April 22, 2015, she tweeted, "Letting go doesn't mean you stop", after a fan created a mock Missing Persons poster of Jackson, which had begun circulating the internet, prompting Jackson to retweet it herself, adding to further speculation of a new album. On May 15, 2015, Jackson announced a new album and world tour. She will release her forthcoming eleventh album in the fall of 2015 through her own record label, Rhythm Nation, distributed by
BMG Rights Management. Later in June 2015, the first 36 dates of the Unbreakable World Tour in North America were announced. Pre-sale tickets were made available exclusively to
American Express and
Citibank cardholders prior to general admission tickets going on sale on June 22, 2015. Jackson's forthcoming album was also made available for pre-order, along with vinyl copies of the album's lead single "
No Sleeep." Jackson enlisted designer
Giuseppe Zanotti to create custom shoes for the tour. In an interview with ''
Women's Wear Daily'' Zanotti stated that "Janet will be dancing a lot on stage as well as singing, so I wanted her to be very comfortable and able to move around easily ... The shoe has to be light but practical and provide support to her feet." Zanotti also noted Unbreakable will be the first tour in which he makes custom designs for the entire cast. ==Commercial reception==
