The actor was seen to have been enjoying himself immensely all evening, with only his encounter with the persistent photographers casting a bit of gloom to his night out. Assuring a male friend at the party, Ifans said: "Don't worry about me everything is OK." When a stunning blonde walked up to him and whispered in his ear, Ifans jokily said: "Maybe later darling... but that's quite an offer."
The 39-year-old actor partied until 12.45am with stars including actress Gwyneth Paltrow, TV host Bruce Forsyth, designer Stella McCartney, comic David Walliams, and singer Nick Cave. "There were loads of women going up to him all night and trying to get his attention," said one partygoer.
"He certainly looked like the cat that got the cream. But, to be honest, he was more interested in chatting to his mates. "He started out necking Old Jamaica Light cocktails before switching to beer he sank at least half a dozen bottles. He was in a great mood," the partygoer added.
