Sabrina Carpenter fans’ imaginations are running wild after the Espresso singer appeared to tease a mysterious new collaboration.

The chart-topping star – who is currently gearing up for the release of her new album Short N’ Sweet on Friday – shared a series of pictures on Instagram on Wednesday morning, alongside the caption: “Taste me!”

One snap in particular has really captured fans’ attention, showing the singer from behind, standing next to a dark-haired female figure.

It didn’t take long for fans to put two and two together and reach the conclusion that Sabrina will be teasing a new collaboration, or at least an interesting co-star in her next music video.

And speculation is already rife about who it could be.

Other names in the frame include Grammy nominee Lana Del Rey, Water singer Tyla or woman of the moment Chappell Roan, whose hit Good Luck, Babe! Sabrina previously covered in Radio 1’s Live Lounge…

Meanwhile, another popular theory has suggested that Sabrina might have recruited Jenna Ortega to appear in her next video, based on a few clues…

And there are also some who reckon Sabrina’s next video will see her simply starring alongside a dark-haired version of herself…

Our favourite comparison of the lot, though, has to be this one…

The caption does hint at a new music video or single, as the opening track of Short N’ Sweet is also titled Taste.

Preceding singles Espresso and Please Please Please have already topped the UK singles chart following their release earlier in the summer.
