'Shark Tank' Star Robert Herjavec Reportedly Dating His 'DWTS' Partner Kym Johnson

Plus Robert admits he was suicidal after his split with his wife of 24 years, Diane Plese.

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.
