Christopher Maloney said it had been an 'emotional day' as he visited his grandmother's grave for the first time in several years.
Patricia O'Brien, died aged 80, in September 2019. She was Chris' number one champion throughout his time on X Factor.
She famously invited X Factor film crews and his then mentor Gary Barlow into her house as part of his homecoming trip in December 2012 and later supported Chris in his showbiz career.
