Inside Janet Jackson’s Grueling Rehearsals, 65-Pound Weight Loss

Janet Jackson is working hard to guarantee her upcoming tour will be “perfection,” a source close to the Jackson family tells ET.

On Monday, the 51-year-old singer showed off her slim post-baby body on Twitter, sharing a pic of herself in rehearsals. Our source says Jackson’s been rehearsing “almost 15, 16 hours” a day in preparation for her State of the World tour, which kicks off in Lafayette, Louisiana, on Sept. 7.

“It’s a grueling schedule but she is up to the task,” the source says. “She wants to blow the crowd away. She will be perfection like her brother, Michael. She’s all about the showmanship.” As for spending time back in Los Angeles after living in London, England — where her estranged husband, Wissam Al Mana is based — the source says Jackson is loving being closer to her family. Thankfully, Jackson and Al Mana appear to still be on good terms.

In May, a source told ET that Al Mana sent his estranged wife a mix of over 100 roses and orchids for her birthday.
