Not even the Grinch could steal this Christmas magic! Saturday night marked a major occasion for the most wonderful time of the year: the Grinch and Cindy Lou Who reunited! That's right! At the Rock & Roll Hall of Fame Induction Ceremony on Saturday, Christmas legends Jim Carrey and Taylor Momsen, who played the Grinch and Cindy Lou in 2000's Dr. Seuss' How the Grinch Stole Christmas respectively, came together for the first time in 25 years!
