Hilary Duff gets beauty tips from her son.
The 27-year-old actress and singer has revealed three-year-old Luca, whom she has with her estranged husband Mike Comrie, is very vocal when it comes to her look and often gives her advice on how she should wear her hair.
She said: "Luca is very particular about how he likes my hair. There's absolutely no buns on my head, no ponytails. I'll have a ponytail and he's like, 'Um, hair down, mum. Hair down, please.' At least he knows what he likes."
The former 'Lizzie McGuire' star - who recently dyed her hair green - was inspired to swap her blonde locks for vibrant aqua tresses after a trip to the beach with her son in Cabo, Mexico.
She explained during an appearance on 'The Ellen DeGeneres Show' last night (30.03.15): "I've never done anything like this.
"I was just in Cabo with [my son Luca] and I was staring at the ocean and I was like, 'I want that on my head.' So, this happened."
Fortunately for Hilary, Luca is a huge fan of her new do.
She said: "He saw [my mermaid hair] and he's like, 'Is your hair green, mom?' And I'm like, 'That's right, it's green.' And he's like, 'Wow.'"
