The spark has gone out!

It's all over for singers Jason Derulo and Jordin Sparks. The couple, who have been together for almost three years, had a mutual break-up and will remain friends.

In an interview yesterday, Jason confirmed the rumours, saying the couple had indeed split but that everything was "cool," adding that it was not a "bad situation".

One of the main reasons behind the split was that the couple weren't seeing enough of each other due to hectic work schedules, said a friend.

Fans will surely find the news difficult to take in, as Jordin and Justin always seemed so totally loved-up. They were very openly affectionate to one another, posting cozy bed selfies, making red carpet PDAs and chatting non-stop about one another in interviews.

At the VMAs last month, the pair even showed up in matching white outfits, with Jordin revealing in an interview that she would be joining her man on his Talk Dirty tour.

Jordin, 24, and Jason, 25, had openly discussed marriage – in fact Jason's hit song Marry Me was about his wish to one day propose. "It is about Jordin, actually," the singer said in a 2013 interview. "And it's talking about how amazing it will be when I get down on one knee and it will be the greatest moment of my life."

The couple had often discussed marriage, according to Jordin. "It's not a conversation that we're scared about," she said. "You really see the people you love and you go, I don't want to lose you," she said when speaking about an incident in which Jason fractured his neck in January 2012.

The two have remained quiet on social media, though last week Jordin did seem more sombre than usual, posting this tweet:

I just wrote the saddest song of my life.

A breakup song perhaps?
