Beyoncé Knowles had an umbrella-holding assistant by her side today in NYC as she juggled her purse and a shopping bag. The expectant singer stepped out in a MOMU charity snakeskin top and bowler hat during the rainy day in the Big Apple, rocking the latest look in the rotation of baby-bump friendly fashions she's sported lately. Beyoncé is launching a maternity line with House of Deréon, the clothing company she runs with her mother, giving other moms-to-be the chance to emulate her pregnancy style. B, who is due in February, has been pursuing plenty of new projects since announcing her baby news in August. Last week she debuted the video for "Countdown" and an early preview of her November Harper's Bazaar cover story was just unveiled on Tuesday.
