Gab time with the gals! Molly Sims was the guest of honor at a baby shower on Saturday, Feb. 7, an insider tells Us Weekly. The model, actress, and designer, pregnant with a baby girl, celebrated at her friend Shannon Rotenberg's Bel-Air, Calif., home.

Sims, 41, looked over the moon as she arrived to the party at 12:30 p.m. She wore a blue and white tie-dyed minidress and kept her luscious blonde waves down.

The Kentucky native was feted by several famous friends at the backyard bash, including Rachel Zoe, film and TV producer Heather Parry, model Kelly Sawyer, and actress Sara Foster. Two brand-new second time moms, Vanessa Minnillo and Ali Larter, also made an appearance. Nick Lachey's wife looked slim just one month after giving birth to daughter Brooklyn. The occasion also marked three weeks after Larter welcomed baby girl Vivienne with husband Hayes MacArthur.

The Las Vegas alum and her guests sipped on mimosas and briefly gathered outside before it began to rain, the source tells Us. Despite the unfortunate weather, the showered-upon shower was decorated with adorable balloons by Geronimo Balloons with bright pink, orange, and yellow tassel tails.

Sims announced in September 2014 that she and her producer husband Scott Stuber are expecting their second child together. The couple wed in September 2011 and welcomed son Brooks in June 2012.

Gearing up for a little girl now, Sims received clothes from Bonpoint, Fred Segal, and Barneys at her shower. As the party winded down around 4 p.m., Stuber and Brooks dropped by to celebrate before heading home with the glowing star.
