The Bachelor alumni may have aired their love story on TV, but they had yet to walk a red carpet together until they stole the show at the 2019 ACM Awards in Las Vegas, Nevada, on Sunday.
The pair stunned in coordinating black looks, with Randolph opting for a metallic silver minidress that criss-crossed with black, gown-length fabric, and Underwood looking dapper in an all-black suit-and-T-shirt ensemble that featured silver chains on his jacket pocket.
The duo even shared a kiss on the red carpet!
Randolph's show-stopping look is no surprise, as Underwood took to Twitter earlier in the week to gush about what his "future fiancee" planned to wear to the awards show.
"Wait till y’all see the dress Cassie is wearing to the ACMs ? - dear lord I’m a lucky guy," he tweeted.
Underwood's date is just one reason why the former NFL player is sure to have a night to remember! The 27-year-old reality staris a huge fan of country music, and ET recently caught up with one of his favorite artists, Russell Dickerson.
Dickerson, who's nominated for song of the year for "Yours" at this year's ceremony, told ET that he met Underwood online after discovering they had mutual friends in common, though they've yet to have an in-person introduction.
"He’s like, 'Dude, your album. I listened to it the entire season.' I was like, 'OK!'" Dickerson recalled of Underwood's message. "We just text back and forth a little bit. He’s super cool."
As for "Yours," a song that Dickerson wrote about his wife, Kailey, the country singer described its success as the culmination of "eight years of working my butt off."
Find out how Dickerson and other nominees fare when the ACM Awards air live from the MGM Grand Garden Arena in Las Vegas on Sunday, April 7 at 8 p.m. ET/delayed PT on CBS.
