Finally! Nicole Richie has confirmed she is pregnant with her and Good Charlotte rocker Joel Madden's baby.

"Yes, I am," Richie told Diane Sawyer during an interiew, which airs in two parts on Thursday's Good Morning America and Friday's 20/20. "We are. I'm almost four months."

What does the future hold for Ms. Richie and Mr. Madden? My pals Stella Starsky and Quinn Cox, authors of the book Sextrology, whipped up an astrological reading on Richie, 25 and a Virgo, and the 28-year-old Madden, who is a Pisces.

If the stars are aligned correctly, it sounds like Richie and Madden could be Hollywood's next power family.

"These two do find each other very intriguing and mostly for the right reasons," Starsky and Cox say.

Virgo women really do like to mother their men, "catering to them and palling around," they say.

Having Richie around so much may prove to be a good thing for Madden, because Pisces dudes like to play savior. "They tend to want rescue women, and they're often attracted to women that are troubled," they say.

But Ms. Richie, whose dating history includes DJ AM, Brody Jenner and a tiny bit of time with Jackass jokester Steve-O, could get a bit too needy if she lives up to her Virgo-ness. That could spell trouble, because Pisces men are often "very detached and really need nothing from other people," they say. Richie, Starsky and Cox fear, may be singing "I Don't Know How to Love Him" from time to time.

Could Richie change? Quite possibly, because Pisces men are sometimes found to be Svengali-like figures and Virgo gals can be more like an "open vessel, tending to let her be made over in a mate's eyes," they say.

As for their parenting, Richie and Madden could turn out to be the perfect good-cop/bad-cop coupling. "Virgo women are often obsessed with their own mothers," Starsky and Cox say. "They tend to want to be friends with their own kids more than mother them in the traditional sense."

Pisces papas, on the other hand, "garner respect through calm," Starsky and Cox conclude. "They can be a formidable figure in a family, someone whose feathers children will be loathe to ruffle."
