Jay-Z dissed no less than eight people - including Nicki Minaj and Kanye 'Ye' West - during his surprise four-minute freestyle rap while headlining the annual Roots Picnic in Philadelphia, Pennsylvania on Saturday.

The 56-year-old rap mogul was seemingly still outraged over Ye's 2025 tweet claiming his two youngest children were mentally challenged, despite issuing an apology weeks later.

'You ever heard of wonder-kin / My children are some of them,' Jay-Z (born Shawn Carter) rapped onstage Belmont Plateau in Fairmount Park in viral footage.

'Have you n****s have no shame / You really wanna get under my skin / I'll really get under ya skin, ask Un how I'm playing.'

However, that didn't stop the 25-time Grammy winner from performing his joint album with the troubled 48-year-old, Watch the Throne, including Gotta Have It and No Church in the Wild.

'It's too far. It's bringing people's kids into it. I don't like that,' Jay-Z told GQ last month.

'Back then, you had the battle, it was fun, and you moved on. Now, I don't know if it can hold up with the technology we have.'

The Roc Nation founder also rapped about Minaj's alleged substance abuse: 'That lady back on that stuff / She like she in love with 'em / Her Ken can't even… / Take they kid... / Enough of them.'

'Ken' appeared to be a direct reference to the disgraced 43-year-old's registered sex offender husband Kenneth Petty being legally barred from picking up their four-year-old son 'Papa Bear' to and from school.

The 12-time Grammy nominee was only 16 when she first met the 48-year-old 'music industry professional,' who served a combined 11 years in prison for raping a 16-year-old girl in 1995 and shooting a man to death in 2002.

Jay-Z also took shots at Trinidad-born Minaj's newfound devotion to all things MAGA after President Donald Trump teased her US citizenship with one of his $1 million gold cards.

'A rapper can't be my opp, I got MAGA Republicans / Them shots came from the very top of the government, good luck with them,' the Brooklyn billionaire said.

The Pink Friday rapper had previously accused her former boss of being a '#ChildPREDATOR' for dating Aaliyah in the late nineties as well as owing her upwards of $200 million in Tidal equity.

After Drake declared 'the jig is up' on 'you OGs' in his new song, Janice STFU, Jay-Z clapped back at his 'little brother': 'My net worth went up again, the next update / The jig is up, n**** I'm up 10 / wrong chart champ, n***** looked up to Hov, I never looked up to them.'

Jay-Z also brought up the Canadian singer's legal war against Universal Music Group CEO Lucian Grainge: 'The crackas got your publishing gangsta, go talk tough to them / Don't talk success to me, you n***** is workers, in perpetuity is how your contract is worded.'

The I Want You Forever rapper called his former Roc-A-Fella Records co-founder Damon Dash a 'chatty patty still down on his luck' in the a cappella freestyle which also took down rapper Oschino Vasquez and gossip blogger Jaguar Wright.

Jay-Z made mention of incarcerated rapper Tory Lanez - who's serving a decade in prison for his role in shooting Megan Thee Stallion - as well as his minister father Sonstar Peterson.

'The Roc's not crumbling / Leprechauns have run out of pranks,' the high-rolling hip-hop star - who ditched his dreadlocks in favor of a fluffy 'fro - rapped.

'Your son in a federal jail mumbling something about having too much in his drink.'

During his 90-minute, 31-song set - Jay-Z admitted he 'missed this s***' and he's next scheduled to perform at Yankee Stadium in New York City's Bronx neighborhood on July 10-12 to celebrate the 30th anniversary of his debut studio album Reasonable Doubt.

The 7 Minute Freestyle rapper hasn't released a full-blown record since his 13th studio album 4:44 in 2017, but he teamed up with his wife Beyoncé on Everything Is Love in 2018.

Jay-Z will executive produce director One9's upcoming Nipsey Hussle docuseries - Hussle - about the Compton rapper who was gunned down, at age 33, in 2019.

The Rock & Roll Hall of Famer still pulls 45.3 million monthly listeners on Spotify, and he's sold over 125 million records worldwide.

On June 13, Jay-Z and his wife Beyoncé Knowles-Carter will celebrate the ninth birthdays of their fraternal twins Sir and Rumi, and they're also proud parents of 14-year-old daughter Blue.

The 44-year-old pop diva was only 18 when she first met the former crack cocaine dealer during MTV Spring Break in 1999, and they've amassed a combined 60 Grammy Awards and $3.8 billion fortune during their 18-year marriage.
