The reports surfaced after McFly heartthrob uploaded a black and white image of Goulding, 29, to Instagram, showing her performing on stage, rocking out while playing the guitar.
Dougie also shared a cute snap of himself clad in cosy pyjamas with Goulding's cat Lennon curled up on his lap, captioning the picture, "Ze cat whispererer".
The pair recently took a break after for over 18 months of dating because of their busy work schedules.
