Kate Hudson's son is "very protective" of her now she is pregnant.

The 'Something Borrowed' star is currently expecting a baby with fiance Matt Bellamy and says seven-year-old Ryder - her child with ex-husband Chris Robinson - enjoys mocking her ever-expanding bump, but also tries his best to take care of her.

She said: "He likes making fun of me. He's a kid, he loves it. He says, 'You're huge!' And all that kind of stuff.

"He's very protective. I put spicy stuff on my food, he goes, 'Mom, don't eat that.' I was like, 'What?' He goes, 'Don't eat that.' This was last night. He goes, 'The baby might not like spicy.' I was like, 'What is going on?'

"All of a sudden he doesn't want me to Drive A car. You shouldn't be driving. I can't get up on anything high. I got up on the thing to get his ball out and he just went, 'Get down.' He's very protective. It's pretty cute."

Kate, 32, feels more settled with her second pregnancy because she has already planned out a living space for the new arrival, something she was unable to do with Ryder.

She told website Starpulse: "It's a totally different pregnancy completely. I mean, couldn't be more opposite, everything.

"This time I'm actually set up, whereas before, I remember with Ryder I didn't even have a nursery. I was trying to get the nursery together. I didn't really have a house until I was seven months pregnant, a home. This time it feels like I actually got to paint a nursery. I actually have a colour in a room.

"I'm going with neutral colour. I don't know what it is so it's neutral. I like yellow. Yellow's a good sunny colour for kids, I think. "
