Jay-Z insists he's only ever had one argument with Solange Knowles.
The 47-year-old rapper was famously caught on camera rowing with his sister-in-law in an elevator after the Met Gala in 2014.
But the 99 Problems hit-maker - who has daughter Blue Ivy, five, and twins Rumi and Sir, two months, with wife Beyoncé - insists the incident was not typical of their relationship.
He said: 'We've always had a great relationship. I fought my brothers and argued with my brothers my whole life. It just so happens, who we are, these things go into a different space, but it ain't nothing.
'We've had one disagreement ever,' he claimed in the new interview, recorded before his headlining gig at the V Festival in Chelmsford, England on Sunday.
And Jay insists things are still 'cool' between himself and the 31-year-old singer and he regards her as his 'sister.'
Speaking on the Rap Radar podcast, he added: 'Before and after, we've been cool. She's like my sister. I will protect her. That's my sister. Not my sister-in-law. My sister.'
Jay went on to praise the 'incredible' work of both his wife and her sister after being asked about the joke that the elevator incident - which was rumoured to have been sparked by him allegedly being unfaithful - had sparked three great albums, his own 4:44, Beyoncé's Lemonade and Solange's A Seat At The Table.
He said: 'I think we went into that elevator great artists. That don't surprise me.
Solange had a surprise hit with her third studio album, released in September 2016, hitting the top of the Billboard 200 album's chart in it's first week of sale. 'I've always loved Solange's music. I think she was slept on before this album. I thought the album before this one was amazing too. Incredible artist.
So I'll be totally honest... I was a little disappointed. Beyonce dropped 'Lemonade' saying Hov cheated... Hov dropped his latest album saying he cheated. So why is he still mum??? I mean I think literally everyone believes that elevator smackdown was over an affair, why not say it? You already admitted to cheating. Can't be any worse than that. Anyways, still can't believe Jay Z cheated on one of the most talented, one of the most beautiful women on the planet and somehow didn't lose her. That's mogul status.
