In this just released promo for the show, Mother Monster appears alongside cast member Kenan Thompson as they "rehearse" for the perfect promo.
Gaga showed off her acting chops on the show during a 2011 appearance when she served as musical guest and Justin Timberlake was the host, so we already know she can act and we definitely know she's got great comedic timing.
She also appeared in a sketch with Madonna in 2009, but that was before...you know, the whole thing.
No word yet on whether or not there will be any other celeb cameos during Mother Monster's SNL takeover, but we'll be watching regardless!
Are you going to watch Gaga on SNL?
