Due to their busy schedules, Ellie and her McBusted beau have been forced to spend more time than ever apart and it's thought the distance has put pressure on their relationship.
So much so, that the couple are said to be taking some time out - despite only recently discussing marriage.
A source told The Mirror: "They are taking a break. Their work commitments have meant they have been spending more and more time away from each other and it has made it difficult to maintain their relationship. They've decided to have a temporary break to see if they can work things out."
"They are both very sad that things have hit a rough patch," the source added. "But are trying to see if a little distance can help them get through it."
News of the pair's split will come as a shock to fans, as Ellie and Dougie had seemed nothing but loved-up lately.
Back in September, Ellie revealed she was ready to marry Dougie.
Opening up about the pair's romance in an interview with Glamour, when Ellie was asked if she was ready to settle down, the starlet replied: "God yes!"
She said: "I'm nearly 30. I once had a pretty warped view of marriage because so many people around me had divorced parents. So for a long time I did think that I'd never get married and that men were sh*t - all that stuff.
"But when someone comes along and re-establishes that trust, then it's nice to think of doing everything the traditional way: having a church wedding, with all my family in one place - I love the idea of that."
Ellie and Dougie first went public with their romance over a year-and-a-half ago in May 2014.
Not only did the duo get matching tattoos during their relationship, but they were often spotted gushing about each other too.
Ellie has joked to fans she was "punching above her weight" by dating the McFly guitarist, while Dougie cutely told his followers he liked Ellie lots on Instagram.
Here's how fans reacted when they heard about the split...
