Lindsay, Paris seen partying

Los Angeles - Lindsay Lohan has been partying with Paris Hilton.

The troubled actress celebrated the completion of filming of her small cameo role in musical TV show Glee by heading to the Bar Marmont, where she stayed until 01:30 before moving on to a house party until 06:00.

According to X17Online.com Paris - who was previously good friends with Lindsay until a falling out - was also spotted at the house in Hollywood Hills and the night before, sparking suggestions the pair may have become friends again.

Lindsay was reported to be a ''total nightmare'' on the set of Glee - which stars Lea Michele, Corey Monteith and Matthew Morrison - because she turned up late and did not know her lines.

A source said: ''Lindsay was a total nightmare. She was three hours late and when she did finally arrive, she just didn't want to be there.''

However, her spokesperson Steve Honig claimed it was simply a misunderstanding.

He said: ''The production team came to us and said that they wanted to start [with Lindsay] right after lunch, which was at 14:00.

"They wanted to begin with Lindsay at 15:00, so that meant she had a lot of time where she wasn't doing anything and that's why people didn't see her.

"She was then in hair and makeup and began after lunch at 15:00."
