Kirsten Dunst and Garrett Hedlund have been happily dating since they met on the set of “On the Road,” but a dating disaster early in their relationship could have sunk their romance.

In a new interview with Details, the 28-year-old Minnesota-born actor talks about how he tried to woo his co-star Dunst back in 2011, taking her out for a romantic canoe ride. But things didn’t go as planned – and the boat capsized. Even worse? It was 3 a.m.

"It was not a stable canoe," Hedlund tells the magazine. "We fell out and had to swim back in mucky, sh---y water, like golf-pond water."

Although the experience left them drenched and dirty, it bonded them as a couple. When speaking about Dunst, 30, to Details, Hedlund affectionately refers to her as “my gal.”

Dunst – who tends to be tight-lipped about romance following her high-profile relationship with Jake Gyllenhaal from 2002 to 2004 – was “a little shy” when it came to talking about her squeeze at the December premiere of “One the Road,” Entertainment Tonight reported at time. However, she did gush about his performance in the flick, which is based on the Jack Kerouac classic and in which they play husband and wife.

"He's amazing in the film," Dunst smiled. "Yeah, of course he's talented. He's very good in this film. It's a very coveted [role], and [they're] difficult shoes to fill.”

Could things between Hedlund and Dunst be getting serious? Well, she certainly has babies on the brain. In an interview with Lucky in 2011, she talked about turning 30, but being worried that guys her age wouldn’t be as ready to start a family as she is.

"I thought when I reached 30 I'd have a lot more figured out," she told the magazine. "Until you have a kid, you're just looking for your partner. And guys have a Peter Pan vibe. They're 35, and they act like they're 25. ...That's what scares me about being in my 30s: not finding someone to have kids with."

The actress, who broke into the movie business at 12, even imagined what her family life would be like. "I can't wait to relive life in a little kid's way," she said. "I'm so ready for that lifestyle: Get a little place upstate [in New York] and have them go to school up there."
