PA

The Made In Chelsea star and Quality Street heiress made the surprise announcement on Twitter last night.

CELEBRITY ENGAGEMENT RINGS

Tweeting an Instagram snap of her new engagement ring, a large emerald-cut diamond set atop two diamond-studded bands, the 23-year-old reality TV star said: "If I could scream loud enough for the whole world to hear I would."

Professor Green, real name Stephen Manderson, popped the question in Paris, having whisked Mackintosh to her "favourite restaurant in the whole wide world."

Meanwhile, the 29-year-old rapper also expressed his feelings about their happy news on the social networking site, too: "Happy days."

In his typical humour, the rapper also sent his sympathies to two Hollywood starlets to whom, he joked he would now have to break the news of his engagement: "Someone's gonna have to break the news to Jessica Alba and Eva Mendez (sic)".

CELEBRITY PROPOSALS

Professor Green and Mackintosh have been dating for a year, having met at the end of 2011 and going public with their romance at the BRIT Awards 2012 ceremony.

No news on a date just yet, but we can bet this is going to be one big, wild wedding.

Congratulations to the happy couple!
