Poor Nathan Sykes of the Wanted. Rumors that the adorbs singer and his equally adorbs lady love Ariana Grande have split surfaced earlier today (Dec. 20). Now it's been confirmed that the singer's grandfather has passed away.

Sykes posted a black and white image of himself and his beloved granddad on Instagram (seen below), writing: "R.I.P. Grandad. Gonna miss you. Hope I can continue to make you proud."

Aw, what a shame, especially so close to Christmas and during the holiday season.

Somehow we think that Sykes doesn't need to worry about continuing to make his grandfather proud, since he's already doing such a good job of that. We don't foresee him doing anything less than totally awesome in his future, since he is so talented and sweet.

PopCrush sends out best out to Nathan Sykes and his family during this tough time.
