The 'Work' singer, whose latest LP Basic Instinct entered the US album chart at number 44, is said to have deleted Hilson from her micro-blogging page after she told radio station Power 105.1: "I would like to do higher that 35k - I mean anyone would."
Ciara later tweeted: "Hear that a newcomer to power 105.1 morning show is really into talking about me! I love it! Keep promoting me! Glad 2 know i mean that much."
She later added: "While were off to this good day, let's have a toast to the douche bags, and have a toast for the assholes!"
Hilson's sophomore effort No Boys Allowed is predicted to sell 100,000 copies this week.
