London, October 8 : Disgraced actress Mackenzie Phillips once worked as a high-class call girl while she was pregnant to pay for her drug habit, according to reports.

The daughter of The Mamas & the Papas founder John previously drew gasps with her new tell-all book ‘High on Arrival’, in which she revealed her father introduced her to cocaine at the age of
11 and she maintained a sexual relationship with him for 10 years.

But a longtime family friend has alleged that the former child star did not bare all her secrets in the tome, including the time she worked as a pregnant prostitute to fund her drug addiction.

"There''s a period in her life Mackenzie completely glossed over in her book. Drugs led her down the path to prostitution,” the Daily Star quoted the un-named insider as telling the National Enquirer.

"Mackenzie fell into a friendship with a Hollywood madam and quickly found work as a jet-setting call girl. She was in her late 20s and pregnant with her son Shane.

"She was shooting cocaine and so strung out she couldn''t get work acting or singing, so she connected with a well-known Hollywood madam. Her clients were extremely high-end and extremely discreet. They''d take her on trips to exotic places. She was arm candy for them.

"... She said the really twisted thing was being hired specifically because she was pregnant. She made a lot of money quickly and used it on drugs," the insider added. (ANI)
