Brooks Nader and Gleb Savchenko perform a hot “DWTS” routine to “Sexual Healing.”

Add fuel to the fire.

Brooks Nader and Gleb Savchenko put on a hot show on Monday's episode of “Dancing With the Stars” amid speculation that the two are more than just dance partners.

The pair coordinated their attire while dancing a “passionate” rumba to Marvin Gaye's “Sexual Healing,” which was a fitting song choice for the flirtatious dancing duo.

At the end of the routine, the 28-year-old Sports Illustrated model appeared ready to smooch her rumored boyfriend.

In the pre-recorded package before her performance, Nader gushed about her connection to Savchenko.

“It’s definitely a big advantage that Gleb and I have such great chemistry,” she said. “So we’re going to use that to our advantage.”

The two received a combined judge's score of 28/40 from judges Carrie Ann Inaba, Derek Hough, Bruno Tonioli and guest judge Rosie Perez.

The rumored pair will have a chance to improve their score on Tuesday when they take on the Cha-Cha.

Nader and Savchenko, 41, have to pick up the tempo as they dance to Poison's “Nothin' But A Good Time” for Hair Metal Night. The rock 'n' roll episode will be judged by KISS legend Gene Simmons as a guest judge.

While the model still needs to work on her footwork, she and Savchenko have no problems when it comes to chemistry.

Since they were announced as partners last month, the two have been packing on the PDA in public and all over social media.

In fact, the couple was spotted kissing during rehearsals ahead of their performance on Week 2 of the hit dance competition series.

In a video shared on social media, the two were chatting backstage when Nader leaned in to kiss the professional dancer, who returned the gesture.

Days later, the duo made no attempt to hide their affection while out and about in Los Angeles.

The “DWTS” partners looked in love as they left Wally's in Beverly Hills, California with their arms wrapped around each other.

As they stopped to share a cigarette, Savchenko placed a hand lightly under his partner's waistband as they shared a passionate kiss. For her part, Nader pulled the dancer closer to him as she wrapped both arms around him.

However, the model later told Extra that there was nothing serious going on between her and her “amazing” partner.

While Nader maintained that the couple wasn't faking anything on camera, she made it clear that they are currently “not in a relationship.”

“Who doesn’t want to make out with Gleb?” joked the influencer.

Nader, who recently divorced Billy Haire, insisted they were “strictly a dancing couple for now.”

“I have so many mixed feelings about it. I'm newly single, so we're having a really nice time,” she said.

“Dancing With the Stars” returns to Hair Metal Night on Tuesday, airing at 8 p.m. ET/PT on ABC.
