It's safe to say Jaimie Alexander and Peter Facinelli's upcoming wedding will be action-packed.

ET caught up with the 31-year-old Blindspot actress on the Golden Globes red carpet on Sunday, when she dished on her upcoming wedding to the 42-year-old Twilight star. The two got engaged in March after nearly three years of dating.

"It's going good," Alexander said about the planning. "We're moving slow because we're both extremely busy right now, but we're coming up with some really fun ideas that involve a bit of a stunt. I'm a big action girl -- I love all kinds of adrenaline stunts so we'll see what happens."

"It'll be something pretty spectacular," she added.

Of course, there's still plenty to be done ahead of the big day. Aside from agreeing that her nuptials will be no ordinary wedding, Alexander revealed that the two actually haven't set a date yet.

"We already feel like we are married, but we haven't done that yet -- we missed a step," she joked.

When ET caught up with Alexander at the Emmys in September, she reiterated that the two were too busy to set a wedding date.

"Who knows, maybe we'll just go to City Hall. Make it easy!" she laughed.

Alexander looked gorgeous on Sunday, rocking a plunging green Genny dress from the label's Spring 2016 collection. She dished to ET that the dazzling dress wasn't exactly the first look she had in mind.

"Well I was going to do a pantsuit, but then I saw this dress, and I said, 'This is the one I'm going to do,'" she shared. "I love green. I'm a huge fan of green, and it's flattering, and it's an extremely comfortable cut."
