Solange Knowles supporting sister Beyoncé ‘no matter what’ as Jay-Z fights rape lawsuit

Family first.

Solange Knowles is “supporting” sister Beyoncé “no matter what” as the “Crazy in Love” singer’s husband, Jay-Z, continues to fight a rape allegation, a source exclusively tells Page Six.

“Solange let Beyoncé know she’s there for her sister and is available to talk anytime she needs,” the insider shares, just days after Jay-Z denied allegations that he raped a 13-year-old girl with pal Sean “Diddy” Combs at a party in 2000.

According to the insider, “Solange reached out to Beyoncé the moment she heard about the allegations.”

Solange’s support comes a decade after her and Jay-Z’s infamous “elevator fight.” Following the 2014 Met Gala, the singer, 38, was seen assaulting her brother-in-law, 55, in a Manhattan hotel elevator as Beyoncé, 43, stood by and watched.

The trio had just entered the elevator after a post-gala party in the Boom Boom Room that evening when Solange immediately launched into Jay-Z, yelling at him and wildly swatting and kicking him.

Jay-Z’s latest scandal involves an accuser — identified only as Jane Doe in the court documents obtained by Page Six — who claims that both he and Combs, 55, raped her at a house party in New York in 2000 when she was just 13 years old.

She claimed the incident occurred at an MTV Video Music Awards afterparty on Sept. 7, 2000 and also involved an unnamed female celebrity who allegedly watched as the rappers took advantage of her.

The Roc Nation founder — who shares daughter Blue Ivy, 12, and twins Rumi and Sir, 7, with wife Beyoncé — has vehemently denied the “heinous” rape allegation, and expressed “heartbreak” for the “Halo” singer and their children in a statement released to Page Six.

The “Empire State of Mind” rapper claimed the lawsuit from Texas-based attorney Tony Buzbee is a “blackmail” attempt.

“What [Buzbee] had calculated was the nature of these allegations and the public scrutiny would make me want to settle,” he said in part in the statement. “No sir, it had the opposite effect! It made me want to expose you for the fraud you are in a VERY public fashion. So no, I will not give you ONE RED PENNY!!”

Jay-Z said the “allegations are so heinous in nature” that the victim should “file a criminal complaint, not a civil one!!”

“Whomever would commit such a crime against a minor should be locked away, would you not agree? These alleged victims would deserve real justice if that were the case,” he continued.

“My only heartbreak is for my family. 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.”

The “99 Problems” rapper added, “I mourn yet another loss of innocence. Children should not have to endure such at their young age. It is unfair to have to try to understand inexplicable degrees of malice meant to destroy families and human spirit.”

Combs has also denied the allegation via his rep in a statement to Page Six.

“Mr. Combs has full confidence in the facts and the integrity of the judicial process,” the statement reads. “In court, the truth will prevail: that Mr. Combs never sexually assaulted or trafficked anyone — man or woman, adult or minor.” 

The Bad Boy Records founder is currently behind bars in Brooklyn, NY, where he is facing a series of sexual assault and sex trafficking allegations, all of which he has denied. He has been denied bail.

Amid Jay-Z’s legal woes, Beyoncé and her husband are proving they’re staying united as a family.

The two were proud parents to Blue Ivy Carter in Los Angeles Monday night as she walked the red carpet for the “Mufasa: The Lion King” premiere at the Dolby Theatre.

“Beyoncé’s sticking by Jay, as evidenced by last night’s family outing,” a source told us, with another adding that she “has no intention” of leaving Jay-Z. “[They’re] a team and will face this situation together.”
