Will Lindsay Lohan be heating up Sundance with Adrian Grenier?

The maybe-couple are expected at tonight’s imawake.com party. The Entourage star is performing with his band, the Honey Brothers. And Lohan, I’m told, is flying in for the shindig.

I'm Awake's goal is to plant 100 million trees by 2020 through its sale of T-shirts, hats and wristbands.

Also expected at the party is Paris Hilton, who was also romantically linked to Grenier this summer. However, Hilton and Grenier have always insisted they were just friends. Grenier was apparently advising the hotel heiress on how to become more green.
