Sounds like Lindsay Lohan's New Year has gotten off on the wrong foot.

While celebrating 2010 on the island of St. Barth's, the 23 year-old star discovered that she was ripped off by her longtime best friend and sidekick Patrick "Pootie" Aufdenkamp.

A friend close to Lohan tells, "Patrick stole Lindsay's sketches for her new 6126 clothing line." WWD reported Dec. 30 that Lohan's 6126 leggings line would be expanded to become a full clothing collection for fall 2010; her role as artistic advisor for fashion house Emanuel Ungaro, despite a rocky start, is also ongoing.

Lohan tells that Aufdenkamp has been her "best friend" since she was 16. He has frequently been photographed with the actress, and was present at many meetings related to her new fashion line.

"He is now running off trying to do his own line," a Lohan pal says incredulously, "And telling people he's going to fashion market week in NYC on February 18 to debut his line."

Adds the Lohan source, "It's horrible. He was her best friend. He has always used her, and she's been warned to never trust him. Lindsay is a good friend and likes to see the good in people. She didn't want to believe how bad Patrick's energy was, and how false his friendship has always been with her."

Lohan herself spoke to exclusively about the sad incident. "I should've known better," she said, noting that the friendship with "Pootie" has ended. "But new year for me and a new beginning! Health, happiness, success and love!"
