The 35-year-old Grammy winner opened up about the first man who gave her that feeling inside during a private show for SiriusXM listeners at the Highline Ballroom in New York City, People Magazine reported.
She said that "This isn't a downer to anybody I dated before him, but I'm just going to be real: I never felt like, honesty, sexually attracted to anybody before him. And I'm not downing my exes. You know, everybody's different. But there was something about him."
"I honestly thought I was asexual-I'd never been turned on like that in my whole life," she added. "I was like, 'Oh that's that feeling...OK! That's what they were talking about in Waiting to Exhale. I just got it. I just didn't have a clue."
The duo first met at the Academy of Country Music Awards in 2006. She was singing a duet that year with Rascal Flatts, and Blackstock was the band's tour manager at the time. "Literally, I'm not joking...he walked by, I was like, ready to take it all off. I just felt something," Clarkson said.
Since, Blackstock was married to actress Melissa Ashworth at the time, nothing happened as Clarkson was quick to mention, she "ain't that girl." She didn't see him again until 2012 after he and his former wife had divorced.
The couple, who got married in 2013, is raising four children together, two from Blackstock's previous marriage and two from their own. (ANI)
