Macaulay Culkin took some time off from injecting himself with heroin to be one of the very few guests invited to her wedding Saturday night. Only 100 guests were there and Macaulay was one of them. They have known each other forever, and when Macaulay and Mila broke up, Natalie was a Macaulay supporter and has not really talked to Mila since unless she had to and that included everything to do with Black Swan. Mac must not be in that bad of a shape if he flew cross country from New York, and got himself down to Big Sur and showed up looking fairly normal at the wedding. A lot of celebrities would have canceled after the week he had so it shows that he is a good friend and wanted to be there for Natalie.
