New Photos! Derek & Julianne Hough — & His Pooch! — Hit The Kia Beach House In Malibu 2

Siblings Derek Hough and sister Julianne Hough at the Kia Beach House in Malibu.

Brother-and-sister duo Derek and Julianne Hough headed to the Kia Beach in Malibu Friday, with Derek’s three-year-old pooch Romy in tow.

The trio spent the afternoon at the house with friends, and they even spotted a group of baby dolphins near the shore. While some party-goers hung out on the beach, the athletically-inclined played tennis.

And like any beach party, snacks and drinks were not in short supply: Party-goers snacked on Sabra guacamole and hummus and Baked By Melissa cupcakes, and downed Hubert’s Lemonade, Zico Coconut Water, Resource Water and Sambazon juice. And to top it all off? Camacho Cigars!
