Mackenzie Phillips, troubled actress, daughter of legendary rocker John Phillips (of The Mamas and the Papas) and older sister of Bijou, revealed that she had a long-term incestuous relationship with her own father in a new book, High on Arrival.

"On the eve of my wedding, [at 19, to Jeff Sessler] my father showed up, determined to stop it," Mackenzie writes in her new novel. " I had tons of pills, and Dad had tons of everything too. Eventually I passed out on his bed... I woke up that night from a blackout to find myself having sex with my own father. Had this happened before? I don't know. All I can say is it was the first time I was aware of it."

And if that revelation wasn't disturbing enough, Mackenzie goes on to chronicle an almost 10-year relationship, in which the father-daughter couple talked about running away to be together.

"One night Dad said, 'We could just run away to a country where no one would look down on us. There are countries where this is an accepted practice...He was completely delusional. No, I thought were going to hell for this."

Mackenzie has wrestled with her demons for years, having been arrested for felony possession of cocaine and in and out of rehab at least 9 times. And, as she tells Oprah in an interview airing Wednesday, "My father shot me up for the first time."

Mackenzie's sister Chynna Phillips (of Wilson Phillips) tells Us about the first time she heard of the incestuous affair, 11 years after it had ended, in 1997.

"Somebody could have dropped a piano on my head and I probably wouldn't have felt it," the singer told the mag. "But I knew it was true. I mean, who in their right mind would make such a claim if it wasn't true?"

Chynna says that upon hearing the news, she went into "a deep, deep sadness and depression for about 10 days. A part of me died when I found out."

"Do I believe that they had an incestuous relationship and that it went on for 10 years?" she went on to say. "Yes."

Yesterday Kourtney and Khloe Kardashian (along with Kourt's babydaddy Scott) were spotted shopping for baby loot in Beverly Hills, and even though Khloe has that quickie wedding coming up this Sunday, it looks like she was able to pencil in some time to help her older sister carry a few shopping bags. Aww, what else are siblings for?

So, we have to ask...any chance Khloe was looking at baby clothes for herself? That spur of the moment wedding definitely has us wondering!

This girl goes through hairstyles faster than most of us change our underwear, but we're kinda digging this latest one! In fact, we'd love to see Rihanna take it one step further and go totally blonde. She's already shaved half of her head and rocked a mini mohawk, so why not pull a Posh (circa 2007) and go platinum? Or should she go back to her roots?

Sarah leaving pilates class on Saturday, September 19, just hours before giving birth!

Sarah Michelle Gellar and husband Freddie Prinze Jr. welcomed a baby girl, Charlotte Grace Prinze on Saturday. This is the first child for the proud parents, and a rep for the actress added that the family is "over the moon."

Aww, congrats! And it's so refreshing to see a celeb couple name their baby something normal for a change!

Our girl's back in LA, y'all!

Brit has been on tour but have no fear - the Circus singer has returned to the City of Angeles (well, Calabasas specifically) and is drinking a Starbucks coffee while wearing a pair of short shorts... what more could we ask for???

Loves the sexy red top, too. Summer might be over, but Britney's sunny personality continues all year round!

Reports say Charlie's Angels star Jaclyn Smith was hospitalized for a bullet wound, in an apparent suicide attempt in Honduras.

Reports say the actress was been hospitalized in San Pedro Sula, after being transferred from the island of Roatan in the Caribbean.

But according to Smith's own Twitter page, the actress is at home, safe and sound.

What REALLY seems to have happened is no less tragic ... Smith's stunt double in the Angels series, Sandra Franklin, is the one who was injured. All of the details seem to apply to her and are, apparently, true.

She may have kept mum on the subject when X17online asked her to confirm that she's preggers today in West Hollywood, but as you can see, a picture's worth a thousand words!

This bump is seriously getting too big to hide, especially when Rebecca insists on wearing dresses/long tops over jeans. And just yesterday Eric issued a telling comment to X17online on how happy he'd be to have a child...guess we know for sure why he was smiling!

X17online was the first to break the news of Gayheart's apparent pregnancy almost a month ago! And even though Rebecca declined to address the obvious, she had an obvious glow, keeping a smile on her face even when we asked her about whether or not she thought that "naked tape" would affect her career!

See how she handled it below...

First of all, how is LiLo paying for all these trips? She's supposed to be broke!

And second of all, what's Ali laughing about? How great it is not to be in school? Such a lucky 15-year-old!

Lindsay Lohan is leaving LA - and all her partying? - behind and traveling to London with her younger sis and entourage. Hey, if you were robbed by someone you know, you might wanna get the heck outta town, too!
