Kathy Griffin was not all too pleased with Ashton Kutcher’s demeanour at a charity event.

Griffin, 56, slams Kutcher in her new book Kathy Griffin’s Celebrity Run-Ins. She describes two different less-than-thrilling encounters with the “Two and a Half Men” star: “We co-hosted a charity event in 2005 for uBid.com. Kutcher, my co-host, did not speak to me once. It was bizarre and rude and made me feel as if he thought I was beneath him.”

And in 2008: “Three years later, I’m grabbing something to eat… and who should walk in but Kutcher and Demi Moore. I smiled and waved. Nothin’. If you won’t say hi to me in the Mexican takeout joint, you’re a d-bag.”
