LOS ANGELES, March 19 (UPI) -- Kym Johnson and Robert Herjavec are reportedly dating.
The 38-year-old Australian dancer and 51-year-old Shark Tank personality are partnered on season 20 of ABC reality competition Dancing with the Stars, and were spotted cozying up at the premiere after-party Monday.
"Kym and Robert were definitely attracted to each other from the get go," a source told the magazine. "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."
Johnson was previously engaged to Australian cricket player Shane Watson, while Herjavec is separated from wife Diana Plese. The former couple married in 1990, and have three children together, daughters Caprice and Skye and son Brendan.
Dancing with the Stars airs Mondays at 8 p.m. ET on ABC. Johnson and Herjavec scored a 28 with their cha-cha to "Bills" on this week's episode, while Val Chmerkovskiy and celebrity partner Rumer Willis earned a 32 with their foxtrot to "Take Me to Church."
