Sheridan Smith has shared rare snaps of her son Billy wearing Sandy Ryan’s World Championship belt.
The three-year-old was in his element as he posed with Ryan following the boxer’s big win last month.
The actress, 41, who is pals with the WBO female Welterweight, joked that the prize was a "bit heavy" for the youngster.
She was hanging out at home with the pair ahead of her latest West End performance.
Smith, who shares Billy with ex Jamie Horn, was all smiles as “AuntY Sandy” later held the huge colourful belt around his waist.
“My lil boy Billy with his Aunty @sandyryan93 our new world champ! We’re so proud of you!” the Cilla star captioned the snaps.
Smith, who is currently appearing in Shirley Valentine in the Duke of York’s theatre, was later joined by the boxer backstage.
The star recently shared snaps of Billy to mark his third birthday earlier this month with a tribute, telling fans he had “changed her life”.
Alongside the photos, The Funny Girl star wrote: “Three years ago today, this little angel changed my life.
“Happy 3rd birthday Billy! You’re my world!”
She spared no expense on his Grand Prix themed bash at a venue in Kent.
