The pop stars have announced they will embark on an extended hiatus following the completion of their upcoming world tour so the singers can also pursue other projects, but the news has sparked rumours they are separating for good.
Gossip about the reasons behind the breakup has also been rampant, with many fans suggesting the singers have fallen out, but Sykes is adamant the rumours are not true.
In a message posted on his Instagram.com page, he writes: "Thank you to everyone for all your lovely messages. We have had the most fun and every moment is down to you guys!
"However, I must take this moment to say that nobody is to blame for any decision we have come to and we are also grateful to everyone who has helped us along the way."
