It’s no wonder Kate Hudson always refused to talk about her romance with Lance Armstrong. (The two recently called it quits after three months.)

“I’ve learned that things are better left private until you’re actually planning the wedding,” Hudson, 29, tells September’s W.

The actress — who also dated Owen Wilson since splitting with ex Chris Robinson in 2006 — insists it’s not easy keeping all the lovey-dovey details to herself.

“It’s so hard for me, because I’m so open, to hold back,” she says. “I could really just go on forever about this stuff.

“We can talk about Chris till the dogs come home. I married Chris, I had a baby with Chris, Chris will be in my life for the rest of my life,” she adds.

She says she has no regrets about spending her 20s tending to son Ryder, 4, instead of hitting the clubs.

“Am I gonna look back and say, ‘God, I wish I could have gone to that… that… concert?” Hudson asks. “I’d rather be listening to my son sing songs. I’d rather be watching him sleep.”

She also revealed the downside to her free-spirited personality.

“I have this thing where it’s like, okay, I’ve chosen to bungee jump off this ledge. I have to do it,” Hudson says. “And if the cord snaps, well, I might as well enjoy the ride down.”
