Looks like multimillionaire tech mogul Robert Herjavec and his Dancing with the Stars partner Kym Johnson are taking their chemistry off-screen as well.

According to multiple reports, the 51-year-old Shark Tank personality and the 38-year-old DWTS pro are dating. The two were "all over each other" behind the scenes and at Monday's premiere party at Hyde Sunset Kitchen + Cocktails in Los Angeles, E! News reports. According to Us Weekly, the two also weren't shy about showing some PDA -- holding hands and dancing closely at the big bash -- where they even "snuck in a couple of kisses."

"Kym and Robert were definitely attracted to each other from the get-go," a source tells Us Weekly. "They are constantly all over each other. She can't stop talking about what a good, nice guy he is. They have insane chemistry and are actually a great match."

Earlier this month, Herjavec confirmed that he split from his wife of 24 years, Diane Plese. In a new interview with People, he admits that he felt suicidal after their breakup.

"I just wanted to end it," Herjavec said about a scary incident last July when he contemplated jumping off the balcony of his Toronto hotel room. "It's been a terribly difficult year. We were great parents and a great team, but over time we drifted apart."

To make matters worse, the couple’s three high school to college-aged children also didn’t talk to him after the breakup. "Everyone has their kryptonite,” he told the magazine. "For me, it was my kids. It took me to a place I never thought I would go."

ET Canada caught up with a clearly more upbeat and hopeful Herjavec with Johnson during their rehearsal before Monday's season 20 premiere, when their chemistry was obvious.

"This couldn't come at a better time in my life for me, right?" he said about his DWTS gig alongside Johnson. "You know, I'm just trying to stay positive and Kym's yelling at me a lot, so that's a little negative, but I'm getting used to it," he joked.
