Despite being spotted kissing backstage at the 'Dancing With the Stars' show, Brooks Nader and Gleb Savchenko — who are partnered together in season 33 — are not letting the relationship rumors get to them.

The 27-year-old model, who is now single following her divorce from Billy Haire, stated in a recent interview, "I kiss everyone I know. All my friends. I love to kiss, so, like, don’t take it to heart. Don’t take offense. It’s just a peck."

Nader peered in and gave Savchenko a kiss as they practiced their quickstep to Dolly Parton's '9 to 5', per OK! Magazine, in the video package that aired before their routine on September 24.

After the show aired, the 41-year-old dancer told Us Weekly, "I didn’t watch the package. And I said to Brooks, ‘Don’t watch the package,’ because I don’t want her to get frustrated, like, messed up or something."

Savchenko further said of Nader, "She loves to kiss," supporting the model's statement.

Since beginning work on the reality series together, the single duo have stirred speculations of romance and even shared what makes them a successful team.

Furthermore, Naders posted a backstage video to social media where her dance partner kissed the model on the head.

The SI Swimsuit model told Fox News Digital during the 'Dancing with the Stars' red carpet, "I'm having the best time of my life. I'm going through recent changes and then being able to hang out with Gleb for five hours a day."

"And… live out my childhood dream of being a dancer on a stage like this is so incredible… Pinch me moment every week… We just have so much fun together… It's such a blessing."

"When you rehearse together for such long hours and days, you create a certain chemistry. Especially like, when we dance together it’s there. We’re trying to get into character pretty much, you know," Savchenko shared his experience to E! News.

"We also are fond of each other," Nader chimed in.
