If staying sober is Lindsay Lohan's main job, it looks like she took the night off over the weekend. The recovering addict partied like it was 1999...and then some at Kim Kardashian's wedding, according to insiders. Obviously, the fact that she even scored an invite to such a revered event was enough reason to celebrate for the washed-up wacktress. The failed Freaky Friday leading lady was decked out in a low-cut white dress and had her bleached blonde hair done in a fancy updo. Despite looking radiant, Lohan supposedly didn't act the part. Fellow wedding attendees maintain that Lohan was back on the bottle. Says one insider, "She was drinking and partying hard. I saw her order shots from the bar." One person who didn't appear to question Lohan's judgment was fellow hot mess and enabler Dina Lohan. She was seated right next to her daughter as she sipped on some cocktails. Lohan is currently on probation and must attend meetings and perform community service. However, there's nothing to say she can't throw back a few drinks...except for some good old-fashioned common sense, which is apparently absent among her circle of family and friends. So far no denials from Lohan's camp that she was getting toasted. In other Lohan news, Lohan and out-of-work late night host George Lopez mended fences at the Kardashian affair. The two have been feuding since last year when the comedian cracked a joke about Lohan snorting coke after she was photographed with baby powder on her shoes. Apparently, all was forgiven Saturday night as Lohan Tweeted to Lopez, "it was lovely seeing you last night and i'm glad we got to "hug it out!" :) xx." He replied with a sincere "Me too xxo."
