Margaret Tomlinson, the mother of the singer's step-father Mark, reportedly passed away last week.
Confirming the news on Twitter, Mark wrote: "The birds are singing today. Rest in Peace my beautiful Mum. I'm going to really miss you."
While Louis' step-grandfather added: "There was never one day in 47 years of being married to me that Mrs T didn't tell me she loved me."
Margaret and Keith Tomlinson became Louis' step-grandparents when their son Mark married the star's mother Johannah when the 22 year old was a toddler.
