Big thanks goes to Kellyann for sharing a link in the previous post that has a date for the world premiere of How Do You Know! The stars will be walking the red carpet to promote How Do You Know on Monday December 13th at the Grauman’s Chinese Theatre in Hollywood. My guess is that Reese will be in attendance, and if she is then you can count on Glamour Reese Witherspoon to bring you all the coverage!
