That's why, as she explained to Us Weekly Tuesday, Dec. 4, at W Hotels, Intel and Roman Coppola's "Four Stories" premiere, she gets on so well with on-and-off boyfriend of nearly two years, Dominic Purcell -- who happens to be 17 years her senior.
"What I like about an older man is that they tend to be your rock," the 90210 actress, 25, told Us. "Whenever I have my crazy [moments], like, 'Ah, this is never going to work out!' Then he's there."
