Masika Kalysha asked Fetty Wap for a paternity test "seven times".
The rapper's on/off reality TV star girlfriend revealed her pregnancy last November and later identified Fetty as the father.
However, while Fetty has allegedly questioned whether or not he is the father of her baby, Masika said she has given him numerous opportunities to prove the paternity one way or another.
She said: "I tried to demand him taking a paternity test. He doesn't want to take one. I asked him seven times, 'Will you just volunteer and do it?' He refuses."
The most recent time Masika asked Fetty for the test was on January 13, but that marked the first time the former couple had spoken in four months - and it was Fetty that initiated contact.
While Fetty and Masika's relationship started as a professional one when they teamed up to make music together, it quickly became personal.
It was when Masika went to get her breast implants removed that she discovered she was pregnant, but she claims Fetty was less than impressed with the news.
She continued: "[He told me] 'Well, I don't really want to have another kid right now'. [Later] He's like, 'Well, if you have this kid, I'm not going to help you out with anything. I'm not gonna be there. You're own your own, so it's up to you.' "
Now Masika is hoping to use her story to help others going through the same situation.
She told Us Weekly: "I know there's tons of women, tons of girls going through something like this. So maybe something I say or something I do with a smile on my face or a tweet that I post, maybe that can help another girl."
