While the details of Natalie Portman's sneak attack marriage toBenjamin Millepied Saturday near Big Sur have been kept relatively quiet, we were interested to hear about one guest in particular who was present at the ceremony:

Macaulay Culkin!

The child actor, who is currently denying allegations that he is battling a severe addiction to heroin, was reportedly in attendance at the nuptials, alongside the couple's family and close friends. If his invite has you scratching your head, don't be! Sources reveal that he and Portman have been "friends for years!"

Just lovely!

We just hope that he managed to put on some weight and clean up a bit since he was LAST spotted by the paparazzi!

Whether or not he's battling some substance issues, we just want him to be HEALTHY!

Congrats again to Natalie and Ben!
