The Wanted are worried about their bandmate Nathan Sykes as he prepares to have throat surgery on his haemorrhaging nodule on his birthday tomorrow (18.04.13).
The 'All Time Low' hitmakers were hoping to record their next album in time for a world tour at the end of the year, but the boys - Siva Kaneswaran, Jay McGuiness, Max George and Tom Parker- are now worried about their future as Nathan prepares to have a procedure on his haemorrhaging nodule when he turns 19 tomorrow (18.04.13), leaving him unable to talk for up to a month.
A source told The Sun newspaper: ''It's not good at all. Nathan has battled with throat issues for a while but this is far more serious.
''After the once-over by the specialist, he was instructed to have almost immediate surgery. Naturally Nathan is really worried as if it doesn't work, his career is over.
''The rest of the band are not only concerned about him but also about the group.
''It will be tricky to continue without him as vocals will have to be changed. All their worldwide commitments are having to be put on hold.''
On top of the surgery, the hunky singer recently called things a day with his girlfriend Dionne Bromfield, Amy Winehouse's goddaughter, but she insists the pair will always remain friends after their brief romance.
She said: ''No we're not dating, not anything. Yeah, it is [hard dating in public eye] but you know, we're really good friends so there are no hard feelings at all.''
