Agron: It's 'sad' to be like Lohan
Dianna Agron has revealed she is cautious of the dangers of celebrity after seeing the plight of Lindsay Lohan.
The Glee star told Cosmopolitan magazine she works hard to keep her personal life secret after watching troubled young star Lindsay live her life in the spotlight.
Dianna said: "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.
"They start not being able to look at you the same way professionally. I don't want that to happen to me."
The 25-year-old actress has always refused to speak about her relationship or split from her I Am Number Four co-star Alex Pettyfer.
Dianna - who has shot to fame playing cheerleader Quinn in hit musical TV show Glee - has since been linked to Captain America: The First Avenger star Sebastian Stan, 27.
The blonde beauty flaunts her figure in a tight white dress on the front of the magazine's September US issue and apparently reveals what she finds sexy in a man.
