The 24-year-old girlfriend of Bill Belichick has applied to trademark the phrase “gold digger”.

Jordon Hudson has moved to cash in on her controversial relationship with the legendary American football coach, 73, on behalf of her company, Trouble Club Enterprises.

She filed the application, which cost $350, to protect her “brand’s unique identity”.

It is just one of a raft of trademark applications she has submitted. Others include “Belestrator”, “Belecast” and “Chapel Bill” – in a nod to Belichick’s current job as coach of the American football team at the University of North Carolina at Chapel Hill.
