Kathy Griffin has branded Ashton Kutcher a "d-bag"

In an extract from her new book 'Kathy Griffin's Celebrity Run-Ins' obtained by the New York Post newspaper's Page Six column, she wrote: "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 ... 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."

Elsewhere in Kathy's book, she relates a tale in which she was backstage at an Eagles concert with Tom Hanks and Harry Styles, and the 'Sully' star joked he'd drive the One Direction singer to rehab because of his drunken conversation.

Recalling the exchange between Harry, who was at the show with Kendall Jenner - who she refers to as Candle - and Tom, she wrote: "Harry: Re-membah when you wuz Forrest Gump? 'Membah? 'Membah?

"Tom, still indulging: I was, yes.

"Harry: You wuz always runnin'? Membah?

"Yes, he was asking Tom Hanks if Tom remembers playing the role of Forrest Gump, for which he won the Academy Award. I can't point out here enough how Harry Styles seemed to think it was his mission to make sure Tom Hanks did not forget the names of any of his films or the fact that he had starred in these films.

"Harry: That was a good film.

"Tom: I do remember.

"Without explanation, Harry Styles turned and pivoted away. Tom Hanks had been pretty much frozen in the same sport during this magical and epic exchange. Tom's answer was perfect and delivered very dryly:

"Tom: Sometimes, I just want to drive them to rehab myself."
