Lindsay Lohan has brushed off speculation she and Jason Segel are a new Hollywood item, insisting the Forgetting Sarah Marshall actor is her "co-worker".

The Mean Girls star sent internet gossips into a frenzy after the paparazzi snapped her leaving Segel's Hollywood home on Saturday morning.

However Lohan, who split from her DJ girlfriend Samantha Ronson earlier this year, is laughing about the fact the duo's business meeting has been mistaken for a romantic rendezvous.

In a post on her Twitter.com page, she writes, "Haha. Now a meeting at a co-worker's home has turned into a new love interest! It's absurd! At least I'm laughing at the rediculous (sic) manifestations."

Lohan has recently been linked to both Gerard Butler and Jessica Alba's husband, Cash Warren.

She responded to comments about kissing Warren in a club, stating, "(It's) absurd. He is married. I wouldn't dare kiss him."
