Professor Green has revealed that he designed his girlfriend's engagement ring.

As previously reported, the rapper recently announced his intention to marry partner Millie Mackintosh after proposing to her in Paris.

Green has been dating the Made in Chelsea star for some time and it seems like the natural next step in the pair's relationship.

Speaking to the Mirror, the rapper revealed that he actually designed the ring which now sits on Mackintosh's engagement finger. He said:

"I chose the diamond, then I designed the whole thing around it. I had to just hope she liked it, too. A bit selfish of me, really."

Speaking meanwhile after being proposed to, Mackintosh had said: "At my favourite restaurant in the whole wide world and then...If I could scream loud enough for the whole world to hear I would."
