Uh-oh. McDonald's has decided to stop using America's favorite Ketchup brand. Why? Well, it has something to do with Burger King.

So, it's been a 40 YEAR partnership. If you're younger than 40 than all you've ever known is Heinz ketchup with your Mickey D's fries. However, McDonald's has decided to end the 40 year partnership because Heinz has a new CEO.

His name is Bernardo Hees...and he used to be the CEO of Burger King. YIKES!

McDonald's said they have many reasons for making the change and Heinz wouldn't comment back.

Apparently, even McDonald's is going to have it their way...
