Monday night's installment of ABC's “Dancing With the Stars” is expected to be unforgettable! And that’s probably because the remaining 10 contestants of Season 20 will each be performing a routine to the Week 4 theme of “My Most Memorable Year.”

While some celebs will honor their careers in tonight’s tribute dance, like “Hunger Games” star Willow Shields and “Three’s Company” actress Suzanne Somers, others will pay respect to their loved ones, such as “Bachelor” star Chris Soules.

According to the 33-year-old contestant, he will devote his “Most Memorable Year” routine to his fiancée, Whitney Bischoff, 29. “Look who dropped by to help me perfect the rumba today!” Prince Farming wrote after he posted an image to Instagram of himself and his soon-to-be-wife at “DWTS” rehearsals. “I’m dedicating this week’s performance to my love @whitb624. It will be my best performance yet. @Dancing ABC.”

Thus far in the 2015 competition, Chris and partner Witney Carson haven’t exactly wowed the judges. In fact, they were the last to be called safe during Week 3 eliminations of “DWTS.” However, Chris and Witney did step up their game last Monday with a “magnificent” Argentine tango that earned them the title of the “comeback kids.” (Tonight's elimination will be based on the combined judges' points and viewer votes that the dancers received for last Monday's performances.)

“You came out there and you were so focused and your intention with every single placement of your foot was on point -- what is it, on fleek? Is that like the new thing? I’m super impressed,” judge Julianne Hough gushed about Chris and Witney's sexy performance.

Chris will continue to strive for success on Monday's episode as he reflects on his proposal to Whitney, dancing to Gavin James’ romantic single “The Book of Love.”

Will Chris Soules pull off a romantic rumba during Week 4 of “Dancing With the Stars”? Sound off in the comments section below with your thoughts and don’t forget to tune in to Monday’s installment at 8 p.m. EDT on ABC.
