Despite the two massive brands working together for a number of years, it has been revealed that a pricing row has come between them, leading to a shortage of Kraft Heinz products on shelves.
This, of course, includes its flagship baked beans, tomato ketchup and mayo.
According to Steve Dresser, CEO of Grocery Insight, cost increases have led to a disagreement between Tesco and Heinz.
Taking to Twitter, he wrote: "A few issues with Heinz lines at Tesco… Some out of stock. Believe there are challenges over cost price increases here."
However, the relationship between Tesco and Heinz appears to remain in tact with hopes of a 'positive resolution'.
A Kraft Heinz spokesperson has said: "We are working closely with Tesco to resolve the situation as quickly as possible.
"In today's challenging economic environment – with commodity and production costs rising – many consumers are working within tight budgets.
"We always look at how we can provide value through price, size and packs so consumers can enjoy the products they love and trust at a price point that works within their budgets, without compromising on quality.
"We are confident of a positive resolution with Tesco."
In a statement given to The Grocer, a Tesco spokesperson has said that they 'will not pass on unjustifiable price increases to our customers'
They added: "We're laser-focused on keeping the cost of the weekly shop in check, offering customers great value through our combination of Aldi Price Match, Low Everyday Prices and Clubcard Prices.
"With household budgets under increasing pressure, now more than ever we have a responsibility to ensure customers get the best possible value, and we will not pass on unjustifiable price increases to our customers.
"We're sorry that this means some products aren't available right now, but we have plenty of alternatives to choose from and we hope to have this issue resolved soon."
Speaking to the BBC, Ged Futter, a former Asda executive and currently the director of The Retail Mind, said pricing disputes are relatively common and it's likely a resolution will be found soon.
"Heinz are saying if you're not prepared to take it (at that price) we will stop supply," he said.
"There will be a resolution as Tesco can't afford not to have Heinz products and Heinz cant afford to not be in Tesco. It's just a matter of what that resolution looks like."
