Dianna Agron talks about keeping personal life private

Although plenty of people like to speculate about Dianna Agron's personal life, she has a good reason for staying tight-lipped about it. In a new interview with Cosmopolitan, the 'Glee' star explains why she likes to keep her private details, well, private.

"It's really sad looking at people like Lindsay Lohan. She's an amazing actress, but you see what happens when people know too much about your personal life," she says. "They start not being able to look at you the same way professionally. I don't want that to happen to me."
In February, the 25-year-old took to her blog to respond to rumors about her reported engagement to 'I Am Number Four' star Alex Pettyfer. "I have been getting a lot of questions about things that I don't feel the need to explain or talk about," she wrote. "I don't mean it as an insult, I've just never shared private details of my personal life to promote my career or a project that I am working on."

Dianna is the cover girl for Cosmo's September issue, which hits newsstands on August 16. Do you think the actress has the right to keep her personal life under wraps or is she fair game because she's a celeb? Let us know your thoughts in the comments.
