After Barbara and her professional partner danced a salsa routine, the 68-year-old real estate mogul and Shark Tank star placed her left hand on Keo's upper thigh when receiving feedback from the Dancing with the Stars judging panel.
The position of Barbara's hand, however, was apparently too close for comfort, sparking a frenzy on social media about how she allegedly grabbed her 27-year-old partner's crotch. Viewers also poked fun at the fact Barbara's hand appeared to remain in that spot for over 20 seconds.
"There was no crotch grab," Barbara insisted to Us Weekly after the show. "I just happened to land my hand on that very important part. And then I felt something in the way, and I moved away."
Barbara also denied grabbing a handful to TMZ, telling the website that she has "better aim than that" and was "reaching for his hand" but "landed on his thigh and hung on for dear life."
During a video package that played before Barbara and Keo took the stage for the first time, Barbara was shown gushing about Keo's good looks -- and he, in turn, joked to the cameras about how the reality TV star is "crazy" and "vibrant."
"I'd be happy with any of the guys here. They're all drop-dead gorgeous, a third of my age... [but] Keo is my type. He's ripped, he's young, and if I married him, I'd probably get 30 years out of the situation," Barbara said.
"I'm going to be the envy of all my girlfriends."
Barbara, however, has been married to former FBI agent Bill Higgins for about 28 years.
"I didn't want [my husband] to interfere in the [Keo] relationship at the get-go," Barbara quipped to Us.
"These things need time to blossom... I asked my husband to move to the guest room and I'm giving Keo comfortable accommodations. I'll do anything for Keo. All the things I used to do for my husband 22 years ago, I'm going to be doing to Keo now."
Keo noted, "I'm going to start writing my list now," to which Barbara replied, "Make your list, baby. Whatever you want. No limit. You want an Aston Martin? You want a home in Malibu? Rolex watches? Don't worry about it."
While rehearsing last week for her Dancing with the Stars debut, Barbara told the magazine, "I feel like I lose my virginity every day in practice. Again and again and again and again."
