The duo were joined by I Am Number Four costar Teresa Palmer at the event.
I Am Number Four hits theaters THIS coming Friday, February 18th — JJJ totally recommends it!
FYI: Dianna wore a lovely Miu Miu dress, a House of Lavande jet Victorian necklace, and Lanvin heels. Teresa was wearing a Julien Macdonald cream silk crepe mini skirt with black lace detail.
