Rachel McAdams Makes Surprise Saturday Night Live Cameo Introducing Reneé Rapp as Musical Guest

The ‘Mean Girls’ actress and singer makes her debut on the ‘SNL’ sound stage

Reneé Rapp had a surprise guest introducing her Saturday Night Live performance — the original Mean Girls‘ Regina George!

Rachel McAdams, who played the role in the 2004 hit movie, made an unexpected cameo on the show to introduce Rapp, 24, who stars as Regina George in this year’s musical remake of the iconic film.

Appearing on stage in a red pant suit and purple roll necked sweater, McAdams, 45, — who starred alongside the likes of Lindsay Lohan, Amanda Seyfried, Lacey Chabert in the original movie — clasped her hands together and grinned as the delighted audience cheered at her surprise presence on the SNL stage.

“Ladies and gentlemen, once again, Renee Rapp!” she said before gesturing over to Rapp, who then began her performance of “Not My Fault” with Megan Thee Stallion, who joined her on stage for the song in another exciting surprise cameo.
