The 'Dancing With the Stars' judge seriously 'can't wait to marry' her man!

Julianne Hough is more than ready to say "I do!"

Ever since NHL star Brooks Laich proposed to the 28-year-old dancer in August 2015, she hasn't been able to contain her excitement over their upcoming nuptials. She took to Instagram on Monday to gush over her soon-to-be husband, dubbing him her "Man Crush Monday."

"#MCM Holy Mother of Hotness! This is MY man!," she captioned a steamy pic of the 33-year-old athlete. "But all sexiness aside, I am the luckiest girl in the world to have you by my side to do life together. Can't wait to marry you! #love #luckyme."

But it takes two to be a #PowerCouple, and these lovebirds certainly fit that description!

Hough looked equally hot on Monday, donning a sparkly midnight blue Martha Medeiros dress, which featured a low back and thigh-high slit, while judging week four of Dancing With the Stars. She completed the ultra-glam ensemble with Neil Lane jewelry and Stuart Weitzman pumps.

ET caught up with Hough during a break from her Move -- Beyond -- Live on Tour rehearsals last month, where she got candid on how wedding planning has been going with Laich.

"It's happening, I'll put it that way," she joked. "This is the time that worked for everybody. It's not necessarily happening soon soon, but it is coming up."

She told ET that while there's a lot to look forward to, she's especially psyched for their first dance.

"I never thought that we would do [a choreographed dance], but [Brooks] really wants to do a first dance and have it be like a special thing," she revealed. "Even before we ever met, as a kid he really wanted to dance. He's always wanted to dance."
