It looks like Lindsay Lohan is back to her old ways as the troubled starlet has been partying hard while in Cannes making friends worry that she is just as "out of control" as she was 2010.

According to RadarOnline.com, the 27-year-old was spotted out at the French film festival on Wednesday night partying at the VIP Room nightclub.

However, it looks like her familiar hardcore partying ways are stressing out her friends who are worried that she has fallen off the wagon once more.

A source close to the "Mean Girls" star told the celebrity news site, "Lindsay is f**ked up and is out of her f**king head," adding, "Lindsay is doing the exact opposite of what she should be doing."

The insider revealed that as of lately Lohan has been hanging with her long-time friend Gavin Doyle, who is all about the French party scene.

Back in 2010 when the redhead was scheduled to be in a Los Angeles court she claimed she lost her passport and in turn begged her friends to fly her home on a private jet however, she failed at this request.

Lindsay Lohan was also reportedly photographed sitting next to a table that had a white substance with lines on it.

An insider revealed, "Lindsay was also with Gavin four years ago," adding, "And now he's with her again. Everyone is worried that she's back partying in Cannes and seeing the pictures of her in the club makes them think that she's surrounding herself with her old friends and that her partying is out of control."

The source explained that not only did Lohan pay for Doyle's plane ticket to Cannes but her friends are now worried "he is enabling her and making a mess of everything."

In an effort to stay clean, Lohan brought her brother, Michael Lohan Jr. on the trip with her. A source admitted, "Her brother is working his ass off to make things work for her and he is basically banging his head against a brick wall," adding, "This is so sad that Lindsay has these horrible people around her again."
