Lindsay Lohan insists on keeping work separate from her personal life - she avoids appearing alongside her friends on camera.
The Mean Girls star, who recently split with girlfriend Samantha Ronson, fears if she encounters any pals on a professional level she will get tired of being in their company.
So the actress deliberately makes sure her filming commitments are friends-free.
Lohan says, "It is better to stay friends with people. When you work with someone, you are with them all the time. Then it gets hard.
"You don't ever want to get to the point where you get sick of your best friend."
Ealier this week it was reported that Lohan looks set to follow in the footsteps of Melanie Brown and perform in a topless show in Las Vegas.
Due to off camera problems Lohan has seen her career slump with her last movie I Know Who Killed Me being universally panned.
