Uh oh: did Jessica Alba just start a catfight?

The mommy-to-be showed off her growing baby bump as she hosted the Lucky Magazine and ThisNext partnership event in a flowing Dolce & Gabbana maxi-dress. Although the pregnant star was already glowing, she added a stack of gold bangles to finish off her summer look.

In April, Dame Helen Mirren struck a pose at the premiere of "Arthur" in London (make sure to check out how to get her look for less). The 65-year-old actress paired her patterned frock with a shrunken black leather motorcycle jacket, also designed by D&G. A safety pin necklace, black clutch and hoop earrings made for the perfect mix of downtown edge and ladylike luxury.
