Zayn Malik is too busy to get married.
The One Direction hunk proposed to girlfriend Perrie Edwards earlier this year, and although the pair originally wanted to wed next summer, the plans are on hold until at least 2015 because of both singers' working commitments.
A source told heat magazine: "Zayn can't set a date at the moment. In fairness, he has no choice as he's too busy next summer and has to see what the band's schedule is for 2015 - but he won't know that until August 2014. So it means Perrie can't even begin to plan things."
Little Mix singer Perrie is said to be upset their big day is so far away, particularly after One Direction fans started tweeting her horrible messages.
The source added: "Zayn's promised to move mountains to get the ceremony on for 2015, but Perrie worries it could be one of those 'showbiz engagements' that never goes the distance.
"She sees a lot of nasty stuff online predicting they'll never tie the knot. She's confident in public about it and says they aren't rushing it, but she's like any other girl who wants to enjoy the build-up to her wedding."
Zayn Malik has chosen his One Direction band mates as his ushers after admitting he can't choose between friends Harry Styles, Louis Tomlinson, Liam Payne and Niall Horan.
Speaking to Yahoo during 1D Day, he said: "It is going to have to be a bit unconventional - it's just not fair to pick one."
His band mates also weighed in on music for the eventual ceremony, with Liam saying Simon Cowell and Ed Sheeran will perform at the nuptials.
He joked: "Simon is going to do a little solo song and we should have Ed there too."
However, Zayn wasn't entirely convinced, admitting Perry would prefer to have Journey front man Neal Schon on hand.
He added: "My missus wants the lead singer from Journey there."
While Zayn is preparing for his wedding day, fellow 'Story of My Life' hitmaker Niall is said to be getting close to 'X Factor' UK contestant Tamera Foster.
According to reports in the Sunday Mirror, the pair have shown "instant chemistry", and she has admitted to getting on well with the star.
She said: "Yes, Niall and I have been talking in private ... I spent most of my time with Niall. He's really fun."
