Julianne Hough wowed fans as Sandy in Fox’s live musical production Grease: Live! on Sunday evening–but probably none more than brother Derek Hough, who gave his Dancing With the Stars costar a big shout-out.
“Killin it ! #GREASELIVE my Sister ! Proud as a mutha,” the Dancing With the Stars pro captioned this short clip of sister Julianne Hough and Aaron Tveit. You can hear the cheering in the background as Hough and his friends watch the production.
A short time later, Derek shared even more of his pride in his sister.
“Singing live for all to hear!!!! Nailed it! #emotional #proudbigbrother,” he captioned yet another clip of Julianne Hough. Listen for Derek’s accolades directed at his sister in the background.
Julianne Hough was like a kid at Christmas ahead of Sunday’s performance.
