It's called Strawberry Swirl, and it looks very similar to the Orange Swirl flavour. Pretty much the same bottle design, only this time red instead of orange.

Those who have tasted it have compared it to the KSI Nightmare flavour, Strawberries and Cream - but with a much stronger emphasis on the strawberry flavour.
At this stage, it looks to be an American-only bottle, and we're not sure exactly which stores are stocking it just yet - but if you find any, let us know, and we'll update this article with the info!
