Rachel McAdams Explains Why She Turned Down Walmart Ad With Her 'Mean Girls' Costars

Earlier this fall, North Shore High School plastics Lindsay Lohan, Lacey Chabert and Amanda Seyfried reunited for a Walmart Black Friday ad.

The commercial also featured Mean Girls originals Rajiv Surendra (who played Kevin Gnapoor) and Daniel Franzese (Damian) and included an appearance by Missy Elliott doing her best Coach Carr.

Notably missing, however, was "Queen Bee" Regina George, played by Rachel McAdams.

In an interview with Variety published on Wednesday, McAdams revealed her reasons for skipping out on the reunion commercial.

She explained that doing commercials isn't really her "bag."

“I don’t know; 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."

McAdams also shared that she only found out after she turned down the offer that her former costars would be in the ad.

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

People on social media collectively agreed her decision was "so Regina George."

Of course, she was still missed, nonetheless.

As for the chatter surrounding McAdams making an appearance in the upcoming Mean Girls movie adapted from the Broadway musical, well, that - like fetch - isn't going to happen, either.

She told the magazine:

“Tina [Fey] 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.”

The new Mean Girls is set to be released in January with Reneé Rapp playing Regina George.
