What Really Went Down With Kiefer Sutherland!

Source reveal exclusively to PerezHilton.com the exact details of the Kiefer Sutherland headbutting debacle from last week!

The incident is being investigated by the NYPD and – if the LAPD gets involved and takes action against the actor for violating his DUI probation – the headbutting could delay production on the new season of 24.

Our sources explains that both Kiefer and Brooke Shields were “drunk as skunks” and partying hard the night of the Met gala. It was then that designer Jack McCollough did in fact bump into Shields and she fell, but it probably had more to do with the fact that she was wearing very high heels and was loaded than the actual shove.

Brooke was fine, but Kiefer insisted that the fashionista apologize. That is when Kiefer Sutherland went all 24 on the guy, even after Brooke told him to ignore it.

Headbutting ensued and we know the rest.

Oh, except that Brooke Shields was such a waste case, she didn’t remember any of this the next morning until she read about .

AND when Kiefer returned after punching McCollough with his face, he had some blood on his forehead.

Says our source, “Brooke was like ‘What is that [to the blood]’? She thought it was a joke or maybe cherry juice and LICKED IT!!!!!”

She liked it!!!! Ewwwwww.

Yuck! That is all kinds of gross. And disturbing. And exactly what you would expect of crazy ass celebrities.
