THE alleged lovechild of Jay Z has hit back at the hip hop star after he appeared to deny he was his dad on his new album.
Rymir Satterthwaite, who has been asking the rapper to take a paternity test for eight years, has released his own rap track in response.
Jay Z released a track on new album Everything is Love, recorded with wife Beyonce - called Heard About Us - in which he raps: "Billie Jean in his prime…For the thousandth time, the kid ain't mine."
Now Rymir has released about how Jay Z has allegedly been trying to stop the 24-year-old making it in the music industry due to the controversial case.
The track even appears to throw shade at Jay Z, 48, with the lines: "N***a wash up still doing tracks, like 55 where f**k you at, need to go back to your old days, grown man in his old ways".
Rymir, who gave an exclusive preview of the track to Sun Online, explained how the song was about how he is "coming for" the music business despite everything.
He said: “This is not me being petty or trying to start a feud or anything like that.
"I want to put my song out there to let the world know I'm still going up regardless what anyone says and Jay Z: I am coming for the music industry.
"If he's said he's not my dad a thousand times - wouldn’t it be easier to just take the test?
"This has gone beyond a paternity test now - it's about more than that."
Rymir’s Promoter Keith McKnight added: "If Jay Z has put his feelings out there in Heard About Us so Rymir should express his feelings through his music too.
"Jay Z is saying he has denied being Rymir’s father a thousand times - well I don’t know who to - because he never said anything to Rymir or his family.
"Why is he on the run?"
Earlier this year Rymir accused the rapper of using his wealth and power to avoid taking a paternity test.
In an exclusive interview with Sun Online in May, he revealed how he was denied a fair hearing in court because of legal mistakes and malpractice - and now wants justice.
Rymir's guardian has even launched a legal battle against their own lawyers - accusing them of colluding with the rapper’s legal team to help him get out of taking the test.
That case was due to go to trial in Philadelphia in December but may now be pushed back to February 2019.
Jay-Z - real name Shawn Carter - has denied being the father but has always refused to take a paternity test.
The court initially threw out Rymir’s request for a paternity test after mistakenly believing his real dad had been found - when in fact he hasn't.
Rymir's birth certificate, seen by Sun Online, shows no dad listed.
Then lawyers for Rymir's side are accused of secretly colluding with lawyers for Jay-Z, causing procedure problems that caused the case to be thrown out of Philadelphia courts, court papers state.
Rymir, from Blackwood, New Jersey, has always maintained he does not want money from Jay Z, who has three children with wife Beyonce, just the right to know who his father is.
“I don’t want money or anything like that from Jay-Z," he said earlier this year.
“I just want him to finally tell the truth to the world.
“He’s supposed to be a positive role model for our community - he stands there screaming ‘Black Lives Matter’ - well tell the truth and take responsibility.
“And if you say I’m not your son and nothing ever happened with my mum then just take the test.
“If you are telling the truth then why is your first answer whenever you’re asked to take a paternity test ‘no’?
"Also I want a fair due process in court regardless of who my father is or how rich he is."
Rymir's mum Wanda told him that she believed Jay-Z was his father when he was around eight.
The 43-year-old claimed that she hooked up with the rapper - then known as “Rock” - in 1992 after he picked her up from Philadelphia and took her to his aunt’s apartment in the projects of Brooklyn, New York.
The pair allegedly used protection but it failed - and aside from a visit from him two weeks later - the pair never saw each other again and Wanda had no idea how to contact him.
Although Wanda's live-in boyfriend Robert Graves was originally listed on the birth certificate - he was legally removed in 2011 after a DNA test proved he was not the father.
What does Jay-Z say about the claims?
Jay-Z has never publicly spoken about the case.
His song Heard About Us, released in June does appear to adress the rumours in the lines: "Billy Jean in his prime...for the thousandth time the kid ain't mine".
Sun Online has reached out several times to his representatives and never received a response.
His lawyer stated that the rapper is "not an interested party with respect to the custody of Rymir Satterthwaite," in legal papers filed in 2011.
He added "there has been no determination or viable claim of a familial relationship with Mr Carter."
Back in 2011 the rap star denied reports he had fathered a different child with a model called Shenelle Scott.
His reps said at the time there was "not truth" to the "ridiculous rumours".
The most recent lawsuit, filed in Philadelphia and seen by Sun Online, claims that one attorney they hired was actually “best friends and neighbours” with Jay-Z’s lawyer.
It claims that Jay-Z's attorney made Wanda sign legal papers while she was in hospital recovering from a medicated coma which replaced Lillie’s name on the petition - without consent - and for “nefarious reasons”.
The name change, done while Wanda was “in distress” and thinking she was doing the right thing for her son, caused the case to be thrown out.
The court papers state that the case has been “devastating” for their family and that “they never saw so much corruption or experienced so much hurt”.
It adds: “Rymir the then-child suffered the pain of rejection, fraud and collusion."
Both attorneys deny the allegations in their response to the lawsuit.
Rymir, who works at a restaurant and a pet store as well as writing and recording music, has said in the past that he doesn't bear a grudge with Jay Z and one day hopes they can resolve the situation.
“If Jay-Z was sat here right now I’d hope we could just talk and catch up," he said.

"I’m a calm person - I’m not going to scream and all that I would just tell him how I feel and hopefully he would tell me how he feels and we could work things out.
“There’s no grudge - I don’t want to have grudges with people in the world that’s why so many people are dying."
