Shemar Moore's got some moves!
The S.W.A.T. star brought Anabelle Acosta as his date to the GRAMMYs in New York City on Sunday -- and told ET's Nischelle Turner about the unexpectedly old-fashioned way his romance with the 30-year-old actress first started.
"I wrote an email. I did that impromptu, chivalry stuff. I took a chance, I took a leap," he confessed. "Mama is fussing at me! But Miss Anabelle Acosta, she's beautiful, look at her."
The two may have already made their debut as a couple, but as Moore confessed, they're still getting to know each other.
"We had never met each other," he explained. "I wrote [the email] just knowing there's no way she's going to hit me back... But I went back to my creative writing classes, I got my mama in my head, 'Show respect,' and I was a poet. Poetry in these fingertips! I wrote a little something something, and I just waited... A few days went by, and then bam!"
"You know what the first thing she said to me [was]?" he continued. "Mr. Shemar Moore, I hear you've been looking for me. Watch yourself!' I was like, 'Oh, it's on!'"
Since that moment, the pair has been "talking for a bit," Acosta revealed. "We're having fun tonight."
"I thought this would be fun. I presented at the Latin AMAs last year. I told him it was stressful, so I didn't get to enjoy the show. So he gets to present [at the GRAMMYs tonight], get the stress this time, and I get to watch the show," the Quantico actress shared.
"I said, 'You want to be spontaneous? You want to do something that most people won't do? You responded to my email. Let's just go big and have fun, because it's a good story,'" Moore added. "It's a good story no matter how it plays out. It's already a great story!"
Moore, who insisted he won't be "the tan George Clooney," also opened up about introducing SZA's performance at the GRAMMYs, revealing that he's already got "a little bit of butterflies."
"If I can get through that teleprompter, it's going to be a good night. I'm going to be at that after-party drinking!" he cracked.
