Kelly Brannigan (born September 18, 1982 in Torrance, California) is an American Model, Actress, and aspiring Singer. To Game Show audiences she is known as Briefcase Model #24 on the NBC Game Show Deal or No Deal.

Born and raised in Torrance, California, Kelly Brannigan and her sister, Sarah, lived with their father until 1993, when he tragically passed away as Kelly and her sister then moved to a small town in Upstate, New York where they lived with their uncle and his wife.

While still struggling to cope with the death of her father, Brannigan found comfort in modeling which quickly became passion, as well with cooking and singing. After college, she decided to pack her bags and moved back to the west coast, Los Angeles to give modeling a true shot. Kelly owes so much to a dear friend of her father, Bill Gow, who helped her through her transition from New York to Los Angeles, and has been extremely supportive.

Kelly also has several hidden talents, one of them is singing (and not only in the shower). She sang opera all through high school and was the leader in her class. She also enjoys cooking, another one of her many passions. Brannigan went to college for two years at Monroe C.C. and studied food service and hospitality. Realizing that cooking was more than a hobby, she enrolled in the Culinary Institute of America for Pastry Arts, but modeling called.
