Aww! They took each other as their dates!
Julianne and Derek Hough were looking too cute at the iHeartRadio Music Awards in Los Angeles!
Letting his sis shine, the 30-year-old looked like prep schooler in his navy Ted Baker London blazer, striped tie, and dark J Brand jeans, while Jules showed off in a sweet white mini dress!
The little number featured a floral design, along with a choker neckline, which she also happened to accessorize with a cream Edie Parker clutch, EF Collection earrings, Zoë Chicco jewels, and simple heels.
Pretty adorable!
