Unlike her first pregnancy, Kate Hudson is well equipped for the arrival of her second child (this one with Muse rocker Matthew Bellamy).

"This time I'm actually set up. Whereas before with Ryder [now 7], I didn't even have a nursery. I didn't really have a house until I was seven months pregnant," the actress told reporters while promoting Something Borrowed in Santa Monica, Calif. on Sunday. "This time it feels like I actually got to paint a nursery. I actually have a color in a room!"

(The 32-year-old mother-to-be chose a neutral color, yellow, because "it's a good sunny color for kids.")

"This is a totally different pregnancy, completely," Hudson explained. "It couldn't be more opposite."

What does Ryder -- her son with ex Chris Robinson -- think about becoming a big brother?

"He's got a sister, but now he's really enjoying it. He like making fun of me," Hudson laughed. "He's like, 'You're huge,' and all that kind of stuff. He's very protective, Ryder is."

How so? "I put spicy stuff on my food and he goes, 'Mom, don't eat that.' I said, 'What?' He said, 'Don't eat that.' This was last night. He said, 'The baby might not like spicy.' I was like, 'What's 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. Like I got up on the thing to get his ball out and he went, 'Just get down.' He's very protective. It's pretty cute."

Though Hudson wouldn't reveal her due date -- "I'm due sooner than later," she teased -- she did put one rumor to rest: "It's not going to be twins!"
