EW! Is this really happening?!
It looks like Sara, erm, Jimmy Fallon is getting a visit from a new friend!
Well, it's Sara's mom's college friend's daughter and Taylor Swift will be playing the part!
We can't wait to see what these two will talk about! Will they talk music? Secret talents? Boyz?? Harry Styles in particular?
LOLz! Whatever it'll be, we're so positive hilarity will ensue!
Ch-ch-check out Natalie's HIGHlarious message to Jimmy (above)!!
