Lindsay Lohan and Lizzy Caplan join Mean Girls fundraising drive

Lindsay Lohan and Lizzy Caplan have joined their Mean Girls co-stars' fundraising drive for the victims of the Las Vegas shooting.

On 3 October (17), which has been dubbed Mean Girls Day thanks to a reference to the date in the film, Amanda Seyfried, Jonathan Bennett, Lacey Chabert and Daniel Franzese launched a GoFundMe campaign and a video in which they called on their fans to donate to help those who had been affected by the shooting at the Route 91 Harvest Festival on Sunday night.

According to Lindsay's representatives, there was such a tight turnaround on the campaign that the organizers were unable to get in touch with Lindsay's team in time for her to be in the original video.

However, once it was published, she reached out to Jonathan to ask how she could get involved.

Lindsay has now recorded her own video message and has also managed to rope in Lizzy, who played Janice Ian, and Rajiv Surendra, who played wannabe rapper Kevin Gnapoor.

"Hey everyone, thank you for donating and happy Mean Girls Day. That was so fetch of you," she said in the video, which refers to many quotes from the movie.

"But we still haven't reached our goal. Don't just watch this video, actually donate. What can I do to prompt you guys?" Rajiv added, before launching into Kevin G's famous "All you sucka MCs" rap.

The video ends with Lizzy channeling Janice while sat in a car and saying, "So please give to this cause. Be a generous person, you know?"

Jonathan tweeted, "EXCITING NEWS!!! @lindsaylohan and TWO surprise guests have something to tell you at" followed by a link to the fundraising page.

They have raised more than $71,000 of their $300,000 goal , which will be donated to the National Compassion Fund and distributed to victims of the tragedy, which left 59 people dead and more than 500 injured.
