Wow, so ya know the Big Mac? It can get even bigger.
McDonald's have revealed that plans are underway to bring a bigger Big Mac - called the 'Grand Big Mac' - to hungry mouths around the UK.
Not only that, but fans of the franchise will also get the Mac Jr.
Apparently they're out tomorrow in the UK to celebrate the burger's 50th birthday.
Of course people took to social media to express their excitement.
One person wrote: "Probably going to have to break my 15 months clean of McDonalds for that Grand Big Mac."
Unfortunately the burger won't be permanent and will only be on sale till 20th March.
We're hoping that NZ gets a taste of this soon (plz!?!?!)
