The press tour has begun for Blake Lively's upcoming movie, The Rhythm Section, and on Monday night, the actor made her return to the red carpet, after giving birth to her third child last year. Lively went all out for the New York screening, delivering old school Hollywood glamour in floor-length black velvet, as Entertainment Tonight reports. She accessorized with thigh-high leather boots, matching leather gloves, and a layered necklace comprising pearls, chains and jewels.
