London: American pop singer and actress Lindsay Lohan is excited about her role as a druggie in the upcoming film titled 'Hippy'.

The 'Mean Girls' star is thrilled about re-teaming with her earlier flick 'I Know Who Killed Me' director Chris Silverstone.

The young starlet said that she has immense faith in Silverstone and loves working with him, and that she is absolutely sure that he would become a big success in the industry.

"I have so much faith in Chris, just as a person, and I just love working with him. I think Chris is going to be huge. I have no doubt in my mind about that," the Sun quoted her, as telling Entertainment Weekly.

'Hippy' is the story of a group of kids on a trip, when one of them starts killing people, under the influence of an acid.

"It's about a group of kids taking a cross-country trip when one of them drops acid, goes crazy and starts, like, killing people," she said.

Lohan, who is currently in Japan modelling for designer Jill Stuart, will begin shooting for 'The Best Time Of Our Lives', which is a biopic based on the love life of poet Dylan Thomas, co-starring Keira Knightley.
