Talk about love at first sight!

Cate Blanchett has been happily married for 18 years. But while her enduring relationship with husband Andrew Upton may be passing the test of time, their courtship, it seems, was much speedier.

The Truth actress, 46, admitted that it took less than a month for Upton to pop the question, but even less time for them to sleep together. After just three days of dating, Blanchett knew Upton was the one – and she realized this while in bed with him.

“No, actually after three days,” Blanchett admitted to Ellen DeGeneres when asked how long they dated before Blanchett knew she wanted to marry Upton. “We were in bed, as you are after three days, and he said, ‘Cate,’ and I thought, ‘S— he’s gonna ask me to marry him and I’m gonna have to say yes.”

Luckily, it was a false alarm. “And then he said, ‘No, I’m hungry, do you want to go get something to eat?’ ” recalled Blanchett, laughing.

But fast-forward less than a month and Upton was ready to put a ring on it.

“Then he asked me after about 21 days and I said yes,” revealed Blanchett.

So how did she manage to lock him down after just three weeks? Her cooking skills. Or lack thereof.

“I cooked him the worst meal. I somehow decided that to stuff a trout with walnuts and goat’s cheese would be a good idea,” she said. “He ate it and then he asked me to marry him, so clearly he was, I don’t know, hallucinating. He realized I couldn’t cook.”

Blanchett added that even though she knew her husband many years before they started dating, it was after those three days – and that horrible meal – that sealed the deal.

“You give them food poisoning,” she joked. “They’re delirious, and then you’ve got them!”

If it wasn’t her cooking that made him fall for her, perhaps is was her endearing collection of embarrassing underwear that did the trick.

“[People] would be horrified if they could see my underwear drawer. I swear to God, the only reason I take jobs and do photo shoots is so I can get more underpants,” she recently told PEOPLE, laughing, at an event celebrating SK-II’s Mid-Day Essence.

“I still have underpants my mother made me in high school. I just – something about going to the lingerie section, I don’t know what – I get overwhelmed, I never know what to buy. So I have the most embarrassing, embarrassing underwear.”
