Lindsay Lohan was one of the hard-partying guests at Kim Kardashian's wedding, an eyewitness tells RadarOnline.com exclusively.
Lindsay attended the bash with her mom Dina and sister Ali. The Kardashian and Lohan families have long been friends, and Lindsay attended Kim's bridal shower a few weeks earlier.
Lindsay wore a low cut Marilyn-style dress with crystal detail in the back. Her blonde hair was styled in a dramatic upsweep.
"She was drinking and partying hard," insider said. "I saw her order shots from the bar."
Mom Dina didn't seem to mind. She was sitting right with her daughters as Lindsay enjoyed several drinks.
Although still on probation, with community service and counseling requirements to be met, Lindsay has no restrictions on drinking and she was not driving.
Lindsay was joined by Eva Longoria, George Lopez, Cheryl Burke, Ciara, Mario Lopez, Avril Lavigne, Serena and Venus Williams, Ryan Seacrest and Julianna Hough in providing star power at the recorded-for-TV wedding.
