Nathan was caught up in series of scandals when he was in the competition.
His ex-girlfriend Jessie fell to her death last May, sparking speculation that their relationship suffered after his participation in the show.
It was later revealed by his late girlfriend’s family that Nathan had borrowed money from her and pressured her to delete photos of them when they were dating.
He withdrew from the finals following the backlash.
Recently, he was reported to be dating starlet Day, who is a member of Hong Kong girl group COLLAR.
The couple have been seen holding hands and going on dates since August, just three months after Jessie’s death.
However, Day has denied that they are dating and Nathan did not respond to rumours.
