In the photo, a smily Joey can be seen sitting in bed, with his pillows thrown on the floor around him.
Alongside the pic, Sam wrote: "Looking after my poorly little patient tonight."
This is the second photo of Sam and Joey together.
Last night (31 March) Joey, 23, shared a cute selfie of them snuggling up in bed.
It has been rumoured that the couple, who were previously engaged, have rekindled their romance after Sam, 23, was diagnosed with Crohn's Disease.
