"I have a lot of respect for Paris. She's ballsy," Grenier tells Page Six Magazine
in its upcoming issue. "She's learned to play with paparazzi attention and have fun with it, and she creates little mysteries in the tabloid arena."
star, 32, continues, "I have fun with her, but it's always been platonic. [Our relationship] wasn't sexual though I understand that sex sells."Grenier recently split
with his girlfriend Isabel Lucas

He was arrested for misdemeanor DUI.
"[Isabel] and I have a very open communication. We're friends with common interests," Grenier tells Page Six Magazine
"If you want to know the whole story, you've got to be my friend. It's easy to put those labels on people, but they're not accurate. We're young in Hollywood having fun."
Meanwhile, Grenier is busy working on a documentary about the paparazzi.
"They're trying to earn a buck in a fun way... so they're doing what they can to feed that demand and make money," Grenier says. "Through my documentary, I've realized how insignificant all that is, because I know who I am. Take one part truth and 1,000 parts speculation and heresy, and you've got yourself a tabloid story."
