Jennifer Aniston seems to be cracking under the pressure of her current high-profile status.

The Friends star - who is currently promoting new film Marley and Me - says that she sometimes wishes people would leave her alone.

Jen told USA Today, "I am honestly getting sick of it, and I feel like telling people, "You know what? It's none of your business.

"Seriously, it's enough."

The actress hopes that new on-screen projects will help to divert attention away from her private life.

She says, "I also haven't had a movie in a long time, so hopefully this is going to create something else to talk about and realize that I have a job, and I'm an actress."
