DJ Khaled has proposed to rapper Nicki Minaj with a diamond ring that reportedly cost $500,000.

The 37-year-old producer and record label executive popped the question to the Starships hitmaker in a short video posted online.

In the 90-second clip Khaled, born Khaled bin Abdul Khaled, professes his love for Minaj and explained to fans why he wants her as his wife.

"I want to be honest with you. I love you. I like you. I want you to be mine," he tells her on camera.

He goes on to admit that their gruelling schedules prevented him from proposing in person and that he is her ideal mate.

"You need a man like me in your life that's gonna take care of you and respect you," he insists.

He continued: "You gotta take your time and think about it, I understand. but I know I have to be here today to let you know how serious I am and about how serious this is to me.

The All I do is Win hitmaker then shows a 10 karat radiant-cut diamond ring from Rafaello & Co before insisting that his intentions are genuine.

"I want to let your fans know, my fans know, my family, your family, that I wanna marry you. I been working hard to get this ring... Nicki Minaj... will you marry me?"

Fans have since reacted to the proposal with a mix of shock and scepticism.

One supporter said: "OMGGGGG O.O NICKIIIII!!!! I wanna kno her answer and btw stop saying stuff like he already rejected, he didnt propose to u stfu if she likes him or w.e its her choice u dont have nun to say bout dat or answer for her. Yall dont kno shit bout how she feels so let them be dam !

Another wrote: "This must be a VMA stunt .This ain't right, Nicki's probably laughing her face off based on how stupid he sounds right now."

A slight hitch to the proposed nuptials is that the blond rapper isn't dating DJ Khaled. But she is currently single, so may be flattered by the offer of wedded bliss. Wait for the sequel on MTV.
