While his band The Wanted is on hiatus, Nathan Sykes has been working on his solo music. The British singer then premiered on Thursday, March 5 his debut solo track called "More Than You'll Ever Know" that's set to be featured on his upcoming album.

The sultry, jazzy song is available as a free download for fans who sign up via his official Facebook. On it, Sykes sounds more mature as he croons about his special lady, "Hey girl I've been thinking of you/ Hey girl I don't want no other/ It's a cold, cold world when I'm without you."

This isn't Sykes' first time to perform a song without his mates from The Wanted. Two years ago, he collaborated with his ex-girlfriend Ariana Grande on "Almost Is Never Enough" off the songstress' debut album "Yours Truly".

Sykes' own debut LP still has no official title and release date, but the singer has said that it will feature contributions from some big names likes of Diane Warren, Babyface and Harmony Samuels. The project's official first single is scheduled to arrive later this spring.
