girlfriend roommate won't mind her own business what should we do about it?

So my girlfriend moved in with her friend since her friend really needed the extra money.
I come and vist my girlfriend from time to time but everytime i do her roommate has something to say. Today her friend for the 2nd time is telling my girlfriend she should make me get a 2nd job and pay all of my girlfriend bills for her, my girlfriend friend also believes i have been using my girlfriend for money yet i haven't ever asked or taken any money for my girlfriend. My girlfriend roommate tried telling my girlfriend as will that she doesn't want me coming over anymore till i get a 2nd job and pay my girlfriend bills who i don't even live with. I feel like her friend needs to mind her own fucking business and stay out of both of are life's. I already help my girlfriend with food and since I'll be moving in with her am now helping with rent. My girlfriend is very independent and loves working 2 jobs she hate staying in 1 place. I am a nursing students and work as a cook so i known am heading down the right path.
