In the ongoing volley of finger-pointing and denials following actress Mackenzie Phillips' shocking allegations that she had been involved in an incestuous relationship with her father, music legend John Phillips of The Mamas & the Papas, Mackenzie's best friend has come out swinging in her defense.

Owen Elliot, the daughter of John's bandmate Cass Elliot tells Extra, "Mackenzie is my best friend. She speaks her truth, and it's not a pretty truth.
