Leading up to his performance with the LA Philharmonic, Dancing With the StarsDerek Hough teased us with hints about what he’d be doing. Though we first expected him to dance, he ended up singing — and blew us out of the water with his performance of “Falling Slowly” from musical Once.

Yesterday night, sister Julianne Hough posted a sweet video of him singing the iconic ballad, and though we didn’t quite tear up while watching, she said he made her cry!

“So proud of my brother @derekhough. He just killed it performing with the LA Phil... You made us cry D man! Love you xoxo,” she captioned the Instagram vid. Aww!

Unfortunately, this was the only video she posted, but we watched it on repeat a few times to make it feel like it was the entire song. According to ABC News, he performed two songs and danced with DWTS troupe member Emma Slater at Dance Fever, so hopefully more photos surface soon!

Until then, check out Julianne’s video of Derek below, then hit the comments with your thoughts!
