Ellie Goulding's boyfriend Dougie Poynter has the look of love on their Highland holiday

Ellie Goulding and Dougie Poynter are clearly vying for the title of pop's sweetest couple. The duo, who've been linked since January, have been keeping fans updated on their romantic holiday in the Scottish highlands with a series of touching instagrams posts.

The 27-year-old songstress shared a picture of her McBusted beau on the train on Sunday, joking: "This guy keeps bothering me on the train its ok though I guess."

In the image Dougie is looking at the camera with the happy, contented look of a guy who has everything he wants in life right there.

Although the couple haven't said too much about their relationship apart from his shy comment that "All is good in that area", they have been pretty much inseparable all year.

A few weeks ago, the hunk supported Ellie at a charity gig Streets of London, which aims to raise awareness and fund support for people who are homeless. She was thrilled to have him on stage with her, telling fans: "Last night was so wonderful".

In the summer the lovebirds had another holiday this time in sunkissed Ibiza. The break followed their appearance at a pre-wedding dinner for his bandmate Danny Jones and fiancée Georgia Horsley.
