Dancing with his sister.
Derek Hough had the best reaction to his sister Julianne Hough flirting with Danny Amendola during the Dancing With the Stars season 33 finale Nov. 26.
Following Danny's Barbie-inspired freestyle dance with partner Witney Carson, the duo laid on a prop bed chatting with Julianne. When the cohost asked Danny, "How is it dancing as Ken?" he responded, "I think the real question, Julianne, is why are you in my bed?"
While Witney simply looked away and said, "Oh," Julianne cheekily said back to Danny with a laugh, "Oh, is that an invitation? Let's get your scores!"
The show then cut to the judges' panel where Carrie Ann Inaba gave them a 9 as Danny and Julianne grabbed one another's hand. The score reveals were then delayed as Derek held up a hand in confusion and playfully asked, "What's happening?!"
His fellow judges then reminded him that he needed to share his score before he flashed a 10 and, in reference to Ryan Gosling's role in the blockbuster, declared "You are Kenough!"
But while the moment was brushed under the rug, perhaps there’s a future duet in store for the former DWTS pro and retired NFL star. After all, Julianne, 36, recently shared that she's single and open to finding a new partner two years after finalizing her divorce from ex Brooks Laich.
"Well, you know, I am single,” she said during the Nov. 19 episode of DWTS, “and I’m looking for a guy anywhere I can find one.”
Meanwhile, Danny—who previously dated Olivia Culpo for three years before their 2018 split—was most recently romantically linked to TikToker Xandra Pohl, who he called simply "a great friend" back in September.
"I’m a huge fan and supporter of her," he told E! News at the time, dispelling romance rumors. "And it’s good to have a friend like her."
