AceShowbiz - Kirsten Dunst and Jesse Plemons are struggling to find time in their busy Hollywood schedules to tie the knot.

The couple shares two sons, Ennis, three, and James, six months, and has been engaged since January, 2017 - but the two haven't found a second to make it to the altar.

The "Bring It On" star would have her nuptials "tomorrow" if she could, but wants to wait and plan a special day to share with friends and family.

"I would marry him tomorrow. We want a proper wedding, we just haven't had the time. And I wanted to have fun at my wedding and not pay for everyone else to celebrate while I am pregnant and waddling down the aisle," she told The Sunday Times Style magazine.

The happily unmarried couple got together in 2016, when playing husband and wife in U.S. TV drama "Fargo" and, although Kirsten felt an "immediate soul connection" with the "Breaking Bad" actor, she insisted it wasn't love at first sight.

"I didn't think love right away. Although one of my best friends told me that I'd said to her, after about two weeks of knowing him, 'I will know him for the rest of my life.' There was an immediate soul connection," she added.

Both Kirsten and Jesse began their careers when they were just three years old and "The Virgin Suicides" standout admitted their own mothers are already desperate for Ennis to start acting too, although she's not quite so keen on the idea.

"I mean, I get it. If he wants to try and it's natural, like if Sofia (Coppola) was doing something, why not?" she shared.

"I am not going to take him on auditions, although both Jesse's and my mother are dying to take him out (to castings)."

"It's what my mum did with me and what Jesse's mum did with him. We won't let them. We joke about it, like, 'You guys should start a children's agency.' And they're like, 'But he has the dimples - this kid would kill it at commercials!' "
