Fetty Wap has denied he’s the father of Love & Hip Hop star Masika Kalysha’s unborn baby and she’s now taking him to court to make him prove it.

The “Trap Queen” rapper denies he could be the father, but Kalysha, who is about eight months pregnant, says he’s the only one who could be. She wants full custody of the baby once she is born.

TMZ obtained the legal documents Kalysha filed that demand him to take a paternity test. Upon proof he’s the father, she wants the rapper to pay child support and expenses for her pregnancy. She claims to spend $17,000 a month on expenses that include rent and clothes.

Kalysha wrote in the documents that she had "sexual relations on numerous occasions” with Fetty Wap between June 28-July 15. She also said he was her only partner during that time and four months before it.

On Feb. 22, it appeared that Fetty Wap had a change of heart when it comes to denying the baby is his because he retweeted a post from Kalysha that acknowledges the baby.

Kalysha also responded to TMZ's story, claiming some of it as false.
