Nina Dobrev strikes a pose at the premiere of Last Night during the 2011 Tribeca Film Festival on Monday (April 25) at BMCC Tribeca PAC in NYC.

The 22-year-old Vampire Diaries star, wearing alice + olivia, recently explained how she juggles playing two different characters, Elena and Katherine, on the CW show.

“I’ve come to the point where I carry around two scripts instead of one, because there were just too many notes, and I couldn’t focus,” she told Zap2It.

“I have this black bound script that says Katherine on it in red writing, and then I have the baby blue script for Elena. It has to be color coordinated. I really have to separate them,” she added.
