The 'On My Mind' hitmaker has been dating the McFly guitarist for over 18 months but admits her relatives still think the pair look like siblings.

When asked what the strangest part of their relationship is, she said: "People always say we look like brother and sister. Even our family members say it. It's quite weird."

The 29-year-old beauty also admits it can be hard dating someone who is just as busy as she is but is glad he can "understand" first hand how she feels when she's had a hard rehearsal or a difficult couple of days travelling.

She added to Glamour magazine: "Dougie and I have such different musical worlds, but he understands when I've had a tough rehearsal or tough couple of days travelling.

"I don't like to rely on him to get me through everything, though. I'm an independent person - I do like to take care of things myself. It's important to figure out ways of keeping your own Zen ...

"I've been busy; he's been busy. We're apart constantly, but we're great because we accept it's never going to be perfect."
