No — there is no reliable public source that currently confirms Debbie Rowe is left-handed.

Debbie Rowe is an American former dermatology assistant, best known as the second wife of pop superstar Michael Jackson. Their marriage lasted from 1996 to 1999.

She is the biological mother of Michael Jackson's two eldest children, Prince Michael Jackson I (born 1997) and Paris Jackson (born 1998).

Rowe maintained a private life for many years after her divorce from Jackson, occasionally making public appearances related to her children or legal matters.

Prior to her relationship with Michael Jackson, she worked for his dermatologist, Dr. Arnold Klein.
