Reese Witherspoon [1] reprised her role as Elle Woods from the 2001 hit Legally Blonde when she stopped by Watch What Happens Live on Thursday. Witherspoon went back to her days as a Delta Nu sorority sister and acted out a famous scene from the movie with host Andy Cohen and her Hot Pursuit costar Sofia Vergara. Cohen put on a blond wig to play Elle's friend Margot, and Vergara was tapped for the role of Elle's other friend Serena. The scene started with Elle announcing to her pals that she's going to law school to win back her ex-boyfriend, but they mistake it for a "vacay." Watch the infamous "road trip!" scene above, then take a peek at Reese and Sofia's adorable friendship [2].
