Rachel McAdams missed the recent Mean Girls reunion because she "wasn't that excited" about signing for a commercial.

Co-stars Lindsay Lohan, Amanda Seyfried and Lacey Chabert who all starred in the 2004 teen comedy got back together to film a Black Friday advert for supermarket giant Walmart, but McAdams was noticeably missing from the line-up - and the actress insists she didn't know the other members of the film's "Plastics" gang had all agreed to take part.

She told Variety: "I guess I wasn’t that excited about doing a commercial if I’m being totally honest. A movie sounded awesome, but I’ve never done commercials, and it just didn’t feel like my bag.

"Also … I didn’t know that everyone was doing it. I would, of course, always love to be part of a Mean Girls reunion and hang with my plastics, but yeah, I found that out later."

McAdams, who played Regina George in the original film, also won't be taking part in a new Mean Girls movie based around the Broadway musical version which was adapted for the screen by the original film's creator Tina Fey.

The actress said she had met with Fey to discuss the project but she wasn't able to commit to joining in. She added: "Tina and I sort of dabbled with a few ideas, but it was tough to make it all work in the end.

"I was really down for whatever she wanted to do. I think the direction it went in will be fantastic and I cannot wait to see it."
