Watch Reese Witherspoon and Jimmy Fallon Mess Up Some Christmas Carols on Purpose

What Scares Reese
Reese Witherspoon reveals her biggest fears in Harper's Bazaar.
Reese Witherspoon got into the holiday spirit with Jimmy Fallon last night when the two of them belted out classic Christmas carols with altered lyrics. (Because there’s always a twist on The Tonight Show).

Witherspoon, who’s been in the Big Apple to promote her new film Wild, was all sorts of adorable for the singing bit, which included some slight harmonizing.

We all know she’s a good singer. But random phrase carols? (That’s what the bit was called). Not so much.

Watch it all go down, above.

Wild opens nationwide on Friday.
