Lawrence, 23, had appeared on the show on November 22 but instead of posing for photographers she tried to sneak out of the back door, reported Us magazine.
While Hoult was casually dressed and clad in a baseball cap, Lawrence was sporting the glamorous cream crop top and skirt she had worn for her interview, under a matching coat.
After meeting on the set of 'X-Men: First Class' back in 2010, Lawrence and Hoult dated for about two years before taking a break in January 2013.
