Mila Kunis says having a breakdown was never an "option" for her.

The 'Friends With Benefits' actress believes supportive family and friends have kept her grounded throughout her career, meaning she wouldn't be the typical young Hollywood star who let her life spiral out of control.

The 27-year-old beauty - who became a teen star after appearing in 'That '70s Show' - said: "There was never an option for me to go into a downward spiral because my parents are incredible people. I went to work, I went home, my friends weren't in the industry. My best friend has been my best friend since I was nine years old. So I never thought of myself as anything other than a 15, 16, 17 year old. What I do and who I am are not the same person.

"But sure, you can get lost in it. And it's less to do with the job and more to do with the world. This industry can eat you alive."

Mila also says she will never let her career take over her life.

She told Britain's Glamour magazine: "No one's curing cancer in this industry, remember? It's not changing the world. It's just entertainment, an art form of escapism. My friends and family are my number one thing in life, but you need a healthy balance."
