Blake Lively is channeling her inner Britney Spears! The actress stepped out to the world premiere of her new film, 'It Ends With Us,' at New York's AMC Lincoln Square theater last night wearing the same glittering Versace dress worn by Spears in 2002. The Versace dress is a one-shoulder evening dress crafted with all-over embroidery and shades of pastels, a dress fit for her character Lily Bloom.
