Rachel McAdams has revealed why she didn’t join a recent Mean Girls cast reunion. In an interview with Variety, the actress commented on the Walmart commercial that brought back Lindsay Lohan, Amanda Seyfried, Lacey Chabert and more as their characters from 2004’s Mean Girls. “I guess I wasn’t that excited about doing a commercial if I’m being totally honest,” McAdams said. “I’ve never done commercials, and it just didn’t feel like my bag.” She added that she “didn’t know that everyone” — including Lohan, Seyfried and Chabert as her fellow “Plastics” — was participating in the ad. “I would, of course, always love to be part of a Mean Girls reunion and hang with my Plastics,” the actress continued. “But yeah, I found that out later.”
