Montag continued to explore her television career, appearing on the series Famous Food in 2011, where she competed for a restaurant partnership. In 2013, she and Pratt participated as a duo on the eleventh series of the British version of Celebrity Big Brother, later returning as All-Stars for Celebrity Big Brother 19.
