The British rapper popped the question to the reality Tv socialite in Paris, France on Monday (25Mar13), and the thrilled bride-to-be immediately took to Twitter.com to upload a picture of her new accessory.
Speaking about his happy news, the hip-hop star reveals he oversaw the design of the sparkler himself after picking the perfect jewel.
He tells Britain's Daily Mirror, "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."
