Will Smith raged at 50 Cent in a series of private messages about his wife Jada's relationship with August Alsina.
The Hollywood actor, 51, and his wife Jada Pinkett Smith, 48, were seen having a tense conversation about their marriage in a dramatic showdown on Red Table Talk last night.
The episode showed Jada confirming she'd had a relationship with singer August Alsina, 27, during a difficult point in their marriage.
After the show aired, 50 Cent reached out to the actor to give his support, but it ended in a furious exchange with Will.
The rapper shared the messages in a post on Instagram, revealing he started out by asking the actor: "Yo Will you alright over there?"
The Independence Day star replied: "Yes, I'm cool. I appreciate your support brother."
50 Cent then pressed him on Jada's comments about August, writing: "But why did she tell you that s**t on a show for everyone to see?"
Will tried to explain, writing: "We broke up so she did her and I did me."
However, the hip-hop star didn't let it go, adding: "Then she said only SHE can give permission for somebody to blow her back out," adding a confused emoji.
Will then got angry with rapper, ending the conversation by writing: "F**k you 50," leaving the star even more baffled.
50 Cent replied: "Wait, what I do?"
He shared the exchange on his Instagram page, insisting he still wasn't sure what he'd done wrong, captioning it: "Damn it’s like that, what I do?"
Will and Jada's marriage hit headlines last month when August gave a bombshell interview about his romance with Jada - claiming he'd had permission from Will.
In a YouTube interview with Angela Yee, he claimed: "I actually sat down with Will [Smith] and had a conversation due to the transformation from their marriage to life partnership.
"He gave me his blessing."
During the Red Table Talk, Will explained how August came into their lives at the time his marriage to Jada had crumbled.
He said: "When Aug first came around, he was really sick. The outpouring for him from our family was initially about his health.
Jada added: "We found all those different resources to help pull from there. You and I were going through a difficult time."
Will explained: "I was done with you... We were gonna separate. You go figure out how to make each other happy... We could be over."
His wife on to explain she then got into a relationship with August, saying: "From there. As time went on, I got into a different kind of entanglement.
