Model-turned-actress Megan Fox has claimed she hides her true self under layers of controversies.

The 23-year-old, who has often caused raised eyebrows after coming out of the closet as a bisexual or for her candid remarks, says it's just an outside persona she has created to veil her true self from getting diluted, reports gossip.ie.

"Being a celebrity is like being a sacrificial lamb. At some point, no matter how high the pedestal that they (critics and audiences) put you on, they're going to tear you down. And I created a character as an offering for the sacrifice. I'm not willing to give my true self up," she said.

"The reality is, I'm hidden amongst all the insanity. Nobody can find me," she added.
