Selma Blair

A big congrats to first-time mama Selma Blair and her boyfriend, Jason Bleick. Their son Arthur Saint Bleick was born 18 days past his due date on Monday, July 26, weighing seven lbs., 12 oz. Throughout her pregnancy, Selma has been one sharply dressed expectant mama! The first-time mom-to-be has made a science out of choosing comfortable, loose-fitting dresses and jeans that maintain her chic, California style during her maternity months. Highlighting her basic threads with bright colorful jewelry and sandals, she looks pulled together whenever we see her. We've pulled together a look back at the star's maternity style — which look is your favorite?

Victoria Beckham and her baby bump were the center of attention at a shower thrown in her honor on the rooftop of LA's exclusive Le Petit Ermitage hotel on Saturday afternoon. Ken Paves and Eva Longoria were the cohosts for the all pink affair with guests Rachel Zoe, Nicole Richie, and Demi Moore there to participate in the fun and themed games. The weekend started off a little rocky for Posh when David and their eldest son, Brooklyn, were involved in a minor highway fender bender Friday, but by later that night she was back to business and joined friends at Buchon for dinner. The following afternoon Eva and Ken suggested Posh wear something "waterproof" for the party, but instead of sacrificing fashion Victoria chose a bright shade of purple for the festive occasion. Fellow fashionable mom Rachel Zoe picked out an ensemble from her own signature collection and accessorized with a Proenza Schouler bag and Chanel sunglasses. Rachel continued her celebrations yesterday at her first Mother's Day brunch at the Chateau Marmont with her family and best friend, and shoe designer, Brian Atwood. Victoria later left the party with a carload full of girly gifts including a Quinny Buzz Special Edition stroller in pink and a 5 ft. custom-made giraffe. Eva went from one party to the next making her way south of the city to Disneyland where she attended the Pirates of the Caribbean: On Stranger Tides premiere later that night.

Selma Blair is one very chic pregnant woman. Her sartorial choices have been rock solid the last couple of months, and even if you aren't pregnant, you can't help but covet her effortless, clean style. Check out our slideshow of our favorite Selma looks these last couple of months, and see what she's doing right.

Selma Blair stopped by an equestrian center in Burbank on Thursday to visit her horse, Taffy. It looks like she and Taffy, who just turned 10, shared a sweet moment together during her time at the stables. The actress has been out and about since announcing her pregnancy in January with her most recent red-carpet appearance at a Lucky Shops LA event last night. She's also front and center in the new ads for H&M's Fashion Against AIDS collection, though the photos were shot before her bump was visible.

A very pregnant Selma Blair held onto her baby bump as she joined Mandy Moore, Whitney Port, and other stylish young women at Siren Studios to help kick off Lucky Shops LA. The weekend sale features clothing and accessories handpicked by Lucky editors, at prices well below retail, and a handful of VIPs were invited to get a preview of the wares on the stylish evening. Whitney debuted a darker hair color as she posed for pictures, while Selma Blair paired a flowing neutral dress with Stella McCartney sandals, and Jenna Dewan went a little wild in a leopard-print caftan. Check out Fab for tips on rocking Jenna's look! Mandy, who has been lying low since her successful Oscars appearance, was on hand to snag a few deals, and her fellow actresses Rashida Jones and Rachael Leigh Cook were also among the ladies who came out to browse the racks.

H&M turned up the volume for its fourth Fashion Against AIDS collection with a cool unisex collection featuring a top-notch list of supporters including Selma Blair, Leigh Lezark and her Misshapes crew, Penn Badgley, Keri Hilson, Sky Ferreira, Akon, Nikki Reed, Ginnifer Goodwin, Scissor Sisters, and Shiloh Fernandez. "I think it's really fitting that this collection is androgynous in style since the disease affects both men and women," said Selma Blair. "It's a universal thing and we are all in this together. It's a disease that can be avoided and it's especially tragic when our ignorance keeps us from safety."

The H&M Fashion Against AIDS collection will be available in H&M's Divided department starting April 26, with 25 percent of sales donated to the charity Designers Against AIDS (DAA) and various international HIV/AIDS prevention projects. Check out the celebs and musicians in the lookbook, plus a piece-by-piece breakdown — including prices — of every item in the collection!

Selma Blair smiled on Thursday while out on a bagel run in LA. The actress, who's expecting her first child with boyfriend, Jason Bleick, also clutched a copy of the book Exploiting My Baby by Teresa Strasser. Selma's working her baby bump into her enviable wardrobe, chic-ly covering her stomach in Lanvin to hit the red carpet at last month's Grammys. She even opted for a two-piece recently for a bikini-filled day at the beach in Malibu.
