Dean McDermott be warned — you and wife Tori Spelling may be happily married and ready to pop out your second child together (it's a girl!), but there could be something she hasn't told you.

"I think if you know everything about your partner’s sexual history, it takes the mystery out of the relationship," Tori told Pop Tarts while promoting her latest chick flick "Kiss the Bride." "So much of that is getting to know your partner and things evolve on the journey. If you know absolutely everything, you don’t learn what you’re supposed to. I don't think you should have to tell everything."

Meanwhile, it seems Spelling has found the answer as to why so many marriages fail. But it took a big white wedding and a dirty divorce to find out.

"Marriage was much easier the second time around; I went through the total freak-out the first time," she revealed. "The first wedding was such a big event. I think big weddings cause people to freak out, which is a bad start in itself."

But making movies (and babies) isn't the only thing the bubbly blonde has been busy doing — she recently released a self-written memoir "Stori Telling" which dishes the dirt on her life growing up in the limelight in that ever-glam 90210 ZIP code.

Spelling also drops the bomb on her mother Candy’s apparent marital infidelity with a family friend during her father’s final days.

"I took so much crap for so long; I needed to get the truth out there so I was brutally honest," Tori added. "But I don't really know what this will do to my relationship with my mother. It’s a grey area we don’t talk about — but it’s been a very complicated 34 years.

"I don't know where this puts us ... in the end people will believe whatever they want to," she continued. "People still perceive me as this little rich girl which isn't the case, but they prefer that conception no matter what I say."

Kat Von D Romping With (Another) Rocker

Some gals just get all the guys, and when it comes to boys in bands, it seems "Miami Ink" starlet Kat Von D has that corner covered.

It wasn't too long ago that she and White Starr drummer Orbison Alexander were getting hot and heavy on red carpets. But Von D rocked on with a new man at Hollywood Life Magazine's 10th annual Young Hollywood Awards earlier this week.

We're told Kat and her new beau, Nikki Sixx (of Motley Crue fame) "couldn't keep their hands off each other" and "were totally gross" at the post-party, their overload of affection peeving off a few party peeps.

However, Mr. Sixx did save the day earlier during the show. "CSI" star Gary Dourdan was originally appointed to present an award to country crooner Taylor Swift, but when he was a no-show, Sixx graciously stepped in.

Well, it turned out that Dourdan had another engagement — a jail cell. The actor was arrested in the wee hours of Monday morning coming home from Coachella music festival in Palm Springs, Calif., on suspicion of possessing cocaine, heroin and other drugs.

"Scary Movie 4" babe Anna Faris also busted out the big guns at the Young Hollywood bash, but apparently her noticeably larger décolletage made heads turn, leaving everyone questioning whether she has recently gone under the knife.

Ryan Gosling Chicked-Off at KFC

Ryan Gosling wants to save the chickens.

Pop Tarts has obtained a letter the Canadian-born actor wrote on Wednesday to John Bitove, CEO of Priszm Income Fund, which operates KFC Canada. We're told the "Lars and the Real Girl" star got mighty mad after hearing about the apparent mistreatment of the chickens in slaughterhouses.

"I understand that KFC Canada is still allowing its suppliers to scald chickens to death in scorching-hot water tanks and that many birds still suffer broken wings and legs because of violent treatment prior to slaughter," Gosling wrote.

"The time is ripe to do the right thing. By adopting the basic recommendations made by PETA and scientific experts (including raising birds in a more natural manner and employing less cruel slaughter methods), you could dramatically improve the lives and deaths of chickens raised and killed for KFC Canada."

Requests for comment from Priszm Income Fund have not yet been returned.

Supermodels' Makeup Artist Spills Skinny Secrets

So a healthy diet and exercise aren't all it takes to look stick-thin on the runway. According to the makeup mastermind behind P3 beauty Terri Apanasewicz, the super-lean likes of Karolina Kurkova, Cindy Crawford and Marisa Miller generally use two foundations so they can use a darker shade just to go beneath the cheekbones to the jawline.

"It makes their faces look thinner and it’s undetectable," Terri said, adding that the girls go gaga about this simple, non-invasive instant shrinking technique.
