Kate Hudson Eager to Expand Her Family with Fiancé Danny Fujikawa at 45

Bride Wars beauty Kate Hudson is the proud mom of three kids with three different dads, but sources reveal the feisty blonde is not done baby-making — even at age 45 — and is eager to drop another bundle of joy!

The gorgeous rom-com queen, who recently switched career gears from acting to singing and released her first album, trills that she would welcome a late-in-life pregnancy with 38-year-old rocker-fiancé Danny Fujikawa.

“I could have so many kids,” gushes Hudson, the daughter of Goldie Hawn. “I even think about it right now, I’m like, ‘Am I totally done?’ Because I can’t imagine being done!”

Kate’s trio of tykes by different rockers have large age gaps between them.

Her oldest is son Ryder, 21, by Black Crowes frontman Chris Robinson — her only hubby — followed by son Bingham, 13, with Matt Bellamy, leader of the English rock group Muse, and 6-year-old daughter Rani with record label owner Fujikawa, her partner of nine years.

“Kate has had seven- and eight-year gaps between children, and with Rani turning 7 later this year, the clock is ticking again,” says a pal.

“And Danny, being younger than Kate, is all for adding to the family!”

The friend adds that Hudson is inspired by other late-in-life celeb moms such as Halle Berry, Rachel Weisz, Hilary Swank and Janet Jackson — who all gave birth at a later age than Kate is now!

But the wanna-baby babe is getting mixed reactions from her current brood.

“When Kate told Ryder she wants to have another baby, he just said, ‘You’re joking, right?’ ” tattles the pal. “He just figured she was trying to get a rise out of him.

“But Rani has bugged her mom about giving her a little brother or sister she can boss around, so no one would be happier than her!”

And the insider insists that Kate wants another kid for all the right reasons.

“She’s always been a doting mom and she’s good at it,” squeals the source. “Doctors have told her she’s in excellent health so there’s no reason she can’t try for another child, even at her age!”
