Mark Lester, 58, claims that Michael Jackson asked him to be his sperm donor The father-of-four says he is the biological father of 19-year-old Paris Jackson Jackson was dating nurse Debbie Rowe at the time, who he divorced in 1999 Lester called Paris 'great looking' and added he 'can't be bothered' for DNA test Neat and handsome, Mark Lester is just as I would imagine a 58-year-old osteopath, acupuncturist and father-of-four to look.
