The 34-year-old judge accompanied 24-year-old Arthur to his local pub where he played a free homecoming gig ahead of the ITV1 show's final this weekend.
The pair were greeted by hordes of hysterical fans who they happily hugged and posed for photographs with.
Arthur also took Scherzinger to the bedsit in the seaside town where he's been living since leaving his home after falling out with his mother, and the pair perched for a heartfelt chat on a bench by the sea front.
Meanwhile in Liverpool, Gary Barlow accompanied his final act Christopher Maloney as he was reunited with his beloved nan at her house in Norris Green.
The X Factor finalists visited Downing Street and met Prime Minister David Cameron as they were invited to switch on the Christmas tree lights last night (December 3).
The X Factor final begins on ITV1 on Saturday at 9pm.
