New York - Janet Jackson on Thursday promised to reschedule a tour of Europe after sudden and repeated delays of shows renewed speculation about her condition.
The pop superstar on Tuesday took off her website all European dates, which were due to begin on 30 March in Birmingham, England, with fans receiving notices that tickets would be refunded.
"You're missing me, I'm missing you," she wrote on Thursday on her website and social media in her first comments on the delay, quoting a lyric from her latest album Unbreakable.
"I'll be rescheduling our Unbreakable shows in Europe as soon as I can. Xoxo," she wrote with no further elaboration.
You're missing me, I'm missing you... I'll be rescheduling our Unbreakable shows in Europe as soon as I can. Xoxo

The 49-year-old sister of pop legend Michael Jackson on Christmas Eve announced that she was delaying the rest of a North American tour but had said she would keep her European dates.
She initially explained that she needed an urgent operation but offered no further detail, although she later denied online rumours that she has cancer.
Jackson's website still lists her US shows, which are scheduled to resume on 14 May in Las Vegas.
The singer, who is married to Qatari businessman Wissam Al Mana, also is slated to perform on 26 March to close the Dubai World Cup horse race.
Jackson reshaped the concert landscape in the late 1980s with her Control and Rhythm Nation tours, which brought together elaborate choreography and upfront sexuality, along with messages of empowerment.
Unbreakable, released last year, was her first album since the death of her brother and her voice at times sounds eerily like Michael's.
She opened her tour on 31 August in Vancouver and travelled across North America and Japan, where she performed her last show on 22 November.
