Alexa Chung changed up her outfit by crossing over her braces, while Emilie De Ravin covered up in a trench as she made her way to mingle with other stars including Emma Watson and Katy Perry who continued to light up the night in her unique dress.

While Joshua Jackson signed autographs, Diane Kruger stood out in a short red dress after the Gala, which she had attended in a long white gown.
