"We are not engaged yet!" the blonde beauty told the magazine of her and Joe's relationship status.
"The ring I wear was actually a gift from my sister. We joke that it's her wedding ring to me because I wear it next to my ring finger and it sort of looks like a wedding ring."
Kendall has an identical twin sister, Kylie, whom she's very close to.
So while the ring does have sentimental value, it wasn't a romantic gift from the former Chicago-based grocery store owner.
However, Kendall and Joe's romance is not at a standstill, as they just recently moved in together.
The pair signed a lease in West Hollywood together at the end of April.
Kendall found fame when she competed for Arie Luyendyk Jr.'s heart on The Bachelor's 22nd season, while Joe was introduced to the world on Becca Kufrin's The Bachelorette edition.
Joe and the taxidermy enthusiast met on Season 5 of Bachelor in Paradise, which aired last summer, but Kendall blindsided and dumped him during the penultimate episode after he professed how he was falling in love with her.
Kendall found herself making a stream of excuses on the beach in Mexico as to why they wouldn't work together, but Joe called her out for simply being unaware of her feelings for him or sabotaging what they had.

Joe therefore left Paradise confused and heartbroken, while Kendall clearly felt there was more she could have said and done.
"I felt an immediate regret as soon as Joe walked away... I kept running away from the fact that I was falling for him," Kendall admitted to People in September 2018.
"I went into Paradise thinking you need to date, you need to be open-minded, you need to experience people... I also had so much fear about getting hurt... It freaked me out to think I would invest myself in him and then it would break apart after the romantic beach vacation was over."
However, Kendall flew straight to Chicago after the show wrapped to talk to Joe again in-person and apologize, and she expressed to him on-camera, "I am in love with you."
It took some time for Joe to trust Kendall again, but the couple ultimately reconciled and reignited the flame of their romance in the real world. Joe, without a doubt, was in love with Kendall as well.
"We don't regret not getting engaged on the show," Joe told Life & Style in December.
"We take it day by day and we really just enjoy hanging out with each other. We don't feel any need for that added pressure of an engagement, but we are solid, so you never know."
