Bruce Willis has been feeling "so much happiness" since becoming a first-time grandad amid his battle with dementia.
The 68-year-old actor became a grandparent last month when his daughter Rumer Willis, who he shares with ex-wife Demi Moore, gave birth to her baby girl Louetta Isley Thomas Willis.
Bruce is said to be a "doting caretaker" to his newborn granddaughter, who is "such a blessing" for the family, according to a source.
