Dianna Agron: "It's Really Sad Looking at Lindsay Lohan"

Dianna Agron sizzles in the September issue of Cosmopolitan, and opens up to the magazine about what she finds sexy in a guy and her surprising bedroom antics. She also talks about keeping her personal life private to avoid the negative attention stars like Lindsay Lohan attract.

Dianna on why she keeps her personal life private: "It's really sad looking at people like Lindsay Lohan," she tells Cosmo. "She's an amazing actress, but you see what happens when people know too much about your personal life."

Dianna adds, "They start not being able to look at you the same way professionally. I don't want that to happen to me."

The sultry Glee star also discusses having the drive to succeed at absolutely anything in the September issue, hitting stands Tuesday, Aug. 16.
