What? Did I read that correctly?

Mackenzie Philips haa a 10 year drug fueled sexual relation with dad. What? Whose dad? 

I actually had to read the paper a few times. Whose dad are they talking about? It took me a while to realize that she was actually talking about her own dad. There must be a typo in the article because this for sure could not be correct. But oh no! Yes, in deed, the two of them had an incestuous relationship for over a decade! This is so repulsing. I'm not even sure why she is revealing this. Some things may be better off left in the closet. 

This for will not be something people forget. So much for the legacy of The Mamas and the Papas.
