Mackenzie attended Highland Hall Waldorf School and soon her talent gained her a spot in the industry but by the early 80’s she had already gained a reputation for being a troubled star.

Mackenzie –who made headlines in 2009 after reveling she had a 10-year long incestuous relationship with her father –currently works at the Breathe Life Healing Center.

Phillips revealed in her memoir High on Arrival that on the night before her first wedding, she woke up to find herself having sex with her own father.


Mackenzie’s first husband was Jeffrey Sessler, the pair tied the knot in 1979 but the marriage only lasted less then two years. They divorced in 1981.
