Gwen Stefani is upping the style ante for pregnant women everywhere. The rocker mom, who is expecting her third child with husband Gavin Rossdale, has been outfitting her baby bump in a slew of stylish designer labels, including Seraphine, Ferragamo, and her own line, L.A.M.B. For her hubby's 48th birthday dinner at Madeo restaurant in West Hollywood, Stefani, with her two boys Kingston and Zuma in tow, topped off her casual cool black, white, and denim ensemble with Stella McCartney’s accessory of the moment: the Beckett bag, named after the McCartney's own son.

Each one is crafted from an environmentally friendly “eco faux nappa leather” material that uses vegetable oils instead of petroleum-based substances. It also folds up like a paper bag to cut down on packaging and shipping costs. Sling it over your shoulder like Gwen, or wear it folded over as a clutch. Get your own ($1,295) in a range of styles and colors at Saks Fifth Avenue and
