Reality stars Chris Hughes, Oliver Proudlock and Joey Essex, and rappers Big Narstie and Lady Leshurr, have partnered with McDonald's to star in the fast food chain's new campaign, promoting the release of the Grand Big Mac and Mac Jr burgers to celebrate 50 years of the Big Mac.

The campaign videos feature the personalities taking part in a 'rap battle', in which they reel off the list of ingredients from the original 1974 Big Mac advert, and Steven Howells, Head of Marketing at McDonald’s UK, commented 'As an iconic McDonald's product, we are proud and excited to be celebrating 50 years of the legendary Big Mac... We know a lot of our customers will remember the 1974 launch of the Big Mac in the UK and have continued to enjoy the burger and pass the Big Mac love on since then, it remains our most iconic burger!'.
