Details are a bit sketchy as to how things kicked off, but we do know it happened at a birthday party in some place called Annabel's in London. Hugh was involved in tete-a-tete (as only the frightfully posh can) near beside the birthday confectionary and ended up getting chocolate sponge "smeared" down the front of his shirt.
Digital Spy reports: "Matthew Freud and Grant became embroiled in a row during the party. Love Actually star Grant, who has been represented by Freud in the past, was said to have ended up with chocolate cake smeared down his shirt and later changed into a clean one."
The Mirror, meanwhile, suggest that Grant called Freud a "c**t", which resulted in the regrettable misuse of chocolate goodness. "Hugh unleashed some serious whoop-ass on PR man. After stamping his foot a bit like a rhino, he charged and delivered an 'impressive' right hook, right in the chops. Describing the punch-up, the PR man (who sounds quite funny) said: 'I saw a lot of white shirt and before I could stop myself it was all brown. I'm a pacifist, I only throw cakes. Grant's a scrapper. There were no heroes'."
Why, I think you'll find there was. Liz Hurley was also in attendance and bore witness to the incident. She was no doubt mentally applauding herself for having the balls to part ways with the oversized child (quite some time) after he was caught with his pants down on some street in L.A. Divine.
