was back on
The Oprah Winfrey Show
on Friday, to continue to talk about her 10-year incestuous relationship with her father John, something half-sister
has now said she knew about.
In a statement Oprah read on the air, Bijou said she was 13 when Mackenzie Phillips told her about the sexual relationship. Bijou is now 29, and says the news was confusing and scary, since it was "heartbreaking" to think her family would leave her alone with her dad.
Mackenzie was not as alarmed, saying John "had changed his ways as much as he was able to" and she felt Bijou was safe, although she would go get get her younger sibling when she "felt like she wasn't being watched properly." It sounds as if the problem is John was watching his daughters all too closely.
