Carmen Bryan, who fell pregnant with Jay-Z's baby during a nine-year affair, has launched an attack against the rapper on Instagram in the wake of allegations that he raped a 13-year-old girl. 

The 52-year-old shared a pointed post, writing: 'These days people don't defend what is right, they defend who they like! And that's why we call you "groupie".'

Carmen, who wrote a book describing herself as the 'hip hop Helen of Troy', also made a jibe at the rapper by highlighting how he referred to himself as a 'rapist' in Kanye West's track Monster.

She posted lyrics from the song, highlighting the lines: 'Kill a block, I murder the avenues, I Rape and pillage your village, women and children'. 

Jay-Z, 55, has been hit with a civil lawsuit that claims he sexually assaulted a 13-year-old girl on September 7, 2000 after the MTV Video Music Awards with Sean 'Diddy' Combs, but denies the allegation and insists he is the victim of a 'blackmail attempt'.

Carmen, who previously worked as an executive assistant in the record industry, fell pregnant during her affair with Jay-Z, which went on from 1995 to 2004 while she was also dating his arch rival Nas, but sadly suffered a miscarriage. 

Their affair continued even while Carmen was engaged to Nas, the father of her daughter Destiny who was born in 1994, but she finally ended things after being left 'disgusted' by Jay-Z rapping about having sex with her in his song Supa Ugly. 

Jay-Z released the track in 2004, and rapped about how he'd had sex with Carmen in a Jeep and left behind used condoms in her daughter's baby seat. 

'Wrong move! That was the moment I lost all respect for SC,' she wrote, referring to the rapper by the initials of his real name, Shawn Carter.

Carmen previously confessed about the affair to Nas after the release of Memphis Bleek and Jay-Z's track Is That Your Chick, a highly sexualised song about stealing another man's partner.

She revealed after the release of the song Nas phoned her to ask if it was about her after years of choosing not to believe rumours between the pair. 

In her memoir It's No Secret, Carmen recalled the difficult conversation with Nas. She wrote: 'Nas, it’s true...The rumours are true. I have been seeing Jay-Z.'

During the 3am phone call, Carmen explained she and Jay-Z had been having an affair for five years after they met as friends and began an intimate relationship a year later. 

In an interview with VLAD TV in 2017, Carmen also admitted she fell pregnant with his baby which she later miscarried. 

'I believe I was three months, it was the first trimester. It wasn't anything crazy, it wasn't planned. It wasn't like "Oh we are going to have this baby".' 

She also confessed she only told Jay-Z about the pregnancy after the miscarriage had happened.  

Discussing Jay-Z's song Takeover which was released in 2001 and was about Carmen, she explained: 'I had already split up from Nas. I had shipped all my things to LA, I moved I packed Destiny and I up, we were already out. 

'Nas and I weren't together. We were not in a relationship,' yet things weren't completely over as she added: 'We were still going back and forth and seeing each other. The relationship wasn't null and void.' 

Jay-Z is the first celebrity to be named alongside Diddy in one of the myriad lawsuits filed against Combs. Both rappers have denied all allegations.

The victim claims the rape took place at a VMA's afterparty in September 2000, while an unidentified female celebrity watched.

The anonymous victim was previously referred to Jay-Z as 'Celebrity A' in the bombshell filing, with the female star accused of watching anonymized as 'Celebrity B.'

Jay-Z issued a blistering response to the lawsuit via DailyMail.com, accusing the victim of attempting to 'blackmail' him.

The rapper claimed he feared that his three children with Beyoncé would have to 'endure' harassment in the wake of the allegations.

Jay-Z said he is especially worried about Blue Ivy, 12, and afraid she will face questions from her friends about the lawsuit.  The couple also share twins Rumi and Sir, seven.

'My only heartbreak is for my family,' Jay-Z told DailyMail.com on Sunday.

'My wife and I will have to sit our children down, one of whom is at the age where her friends will surely see the press and ask questions about the nature of these claims, and explain the cruelty and greed of people.'

Jay-Z said he mourned 'yet another loss of innocence' and declared that his 'children should not have to endure' the graphic accusations at their young age.

'It is unfair to have to try to understand inexplicable degrees of malice meant to destroy families and human spirit,' he said.

Beyonce and Jay-Z have been an R&B power couple for more than 20 years. They got married in April 2008, and by April 2014.
