Robert Herjavec hints at romance with Kym Johnson

LOS ANGELES, April 7 (UPI) -- Robert Herjavec says he and Kym Johnson share more than just dancing.

The 51-year-old Shark Tank personality hinted at a romance with the 38-year-old Australian dancer in an interview with Good Morning America on Monday. Herjavec and Johnson are currently partnered on Dancing with the Stars, and many speculate the two are also dating.

"She's a great dancer and she's become a great friend," he conceded to correspondent Rachel Smith, while keeping mum on their relationship status. "It's more than just the dancing. I think we just get along great!"

Herjavec and Johnson sparked speculation after cozying up at the ABC reality competition's premiere after-party in March. The pair previously addressed dating rumors by coyly saying they are "too busy dancing" to pay attention to such reports.

Herjavec and Johnson have done well in competition, scoring a 28 with a cha-cha in week one, a 28 with a foxtrot in week two, a 29 with a rumba in week three and a 34 with a waltz this week. Dancing with the Stars airs Mondays at 8 p.m. ET.
