The Atlanta-based beverage giant is relaunching its classic Diet Coke formula - along with four new flavors - in taller, thinner cans.
Coca-Cola North America group director for Diet Coke Rafael Acevedo says it's simply modernising Diet Coke by making the brand more relatable and more authentic.
So whether you're a longtime fan, or just the type who's down to try new things, give Diet Coke a taste and you'll see what we're talking about.
Because after speaking to more than 10,000 people and spending years exploring all kinds of combinations like tropical, citrus and even botanical notes, we found magic.
Diet Coke has not yet responded on Twitter, so we suspect that this war will fizzle out soon.
In the tweet, Lime-A-Rita suggests that Diet Coke created something very similar to their flavors and can styles.More news: US Army challenging nickname of NHL's Las Vegas franchise

The company has unveiled a new design for the low-sugar drinks brand in the United States market, and introduced four new flavours.
'We believe that to recruit a new generation, we have to appeal to them, and millennials are 40 per cent multicultural'.
Sommerville now says the design team have an opportunity to rethink such an iconic brand with the scale and reach of Diet Coke.
The redesigned cans will retain the brand's silver and red colouring, with different coloured accents for each of the new flavours. A slightly refined typography simultaneously preserves Diet Coke's heritage, yet presents it in a more progressive manner, according to the company.
Diet Coke will also continue to be offered in its existing package sizes, including standard 12-oz cans, mini cans, and glass and plastic bottles. "We're building a portfolio for the future with great-tasting options people want".
