Last month, we revealed that mommy-to-be Nicole Richie was collaborating with A Pea in the Pod on a maternity line. Now, the capsule collection has officially launched with a star-studded fête in Beverly Hills, of course!

A very preggers Richie attended the party in her own designs: She paired a cream and black floral print silk top by "Nicole" for A Pea in the Pod with a simple, yet short and stylish black dress.

If the sophisticated and chic look was any indication of the exclusive maternity collaboration, then it looks like Richie is once again proving her talents as a designer -- House of Harlow 1960, anyone?

On her collection that is now available online, Richie says, "I hope that the ease and comfort of my designs will help expectant moms to look and feel amazing throughout their pregnancy."

And with it being LA and all, the launch party had stars aplenty: Maria Menounos and Ali Landry stopped by, as did several pregnant actresses, including Jaime Bergman, Tisha Campbell Martin and Nicole Sullivan.

With droves of Victoria Secret models jumping on the baby-on-board train and Cynthia Rowley announcing a kiddie line with Babies"R"Us, it looks like a newborn is fall's chicest accessory. "It" bag? Try "diaper" bag!

    Allen recently told Britian's More magazine that she doesn't feel comfortable modeling. "It's not something that comes naturally to me, especially when I'm working with fashion photographers because they're used to working with really tall, skinny and beautiful models and I'm very aware that I'm 5'2" and a size 12." Not comfortable? Could have fooled us.
