Rapper Curtis James Jackson III, better known as 50 Cent, says singer Beyonce Knowles once confronted him for getting into an argument with rapper-record producer Jay Z and "jumped off a ledge" to defend her husband.

The rapper was shocked when Knowles "jumped off a ledge and came running over" to defend her husband at the Cosmopolitan Hotel in Las Vegas, reports femalefirst.co.uk.

"One time (Knowles) jumped off of a ledge and came running over cause she thought me and Jay had issues. And I'm like, 'What the f***? Did she really just jump and run up on me like that?'," said 50 Cent.

Knowles became very protective of Jay-Z because she thought things were about to turn physical between the two rappers, but they soon laughed off the dispute.

"She jumped out and I was like this, 'What?! That Bonnie and Clyde for real! You try this or what, boy?! I'm here!' She bugged out at me. I looked and Jay starts laughing. He's like, 'Yo, you know what it is'," said 50 Cent.
