In February, the "Love On" singer opened up about how the trio's bond has transcended off-screen while appearing on Jimmy Kimmel Live! "Our dynamic [on-screen] is actually very truthful in a way," Gomez told Jimmy Kimmel. "They're hilarious. Everything I do with them is just a fun experience." The Wizards Of Waverly Place star added that she was aware of some of the actors' work before OMITB began, including Martin's hit movie Father of The Bride and Short's character Jiminy Glick from the shows Primetime Glick and The Martin Short Show. "They tell me the craziest stories about just how different life was back then and it seemed a lot less chaotic than it is now," she laughed.
