The Big Mac has long been a firm favourite for McDonald's fans, and now the famous burger has gotten even bigger!
The fast food giant has created a 'Grand' Big Mac. The massive burger consists of two 100% Irish beef patties, a slice of cheese, lettuce, onion and pickles and Big Mac sauce in a sesame topped bun and contains 740 calories.
McDonald's has also launched a Mac Jr - a smaller version of the burger which has one meat patty instead of the usual two and contains 400 calories.
The burgers are available for a limited time only, from February 7th until March 20th.
McDonald's has also released a limited edition Malteasers McFlurry, Mozzarella Dippers and The Sticky Sweet BBQ Chicken.
