Gwen and Gavin took their sons for a fun-filled afternoon at the Air & Space Museum in NYC yesterday, letting Zuma test out his pilot skills in the cockpit of a plane and giving Kingston a loving lift in the air. Gwen is in town for Fashion Week and brought her boys along for the ride. She's set to debut her first-ever fragrance, Wicked Style, during FNO on Friday and has her L.A.M.B. runway show on Sept. 16. The musical mom spent most of her Summer close to home, taking the kids to Disneyland, relaxing on the beach, and celebrating little Zuma's second birthday. While it's back to business for Gwen, she and Gavin capped off the season by watching their friend Roger Federer compete at the US Open last weekend.
