Derek Hough and his sister Julianne joined Maria Menounos and other celebrities as they attended a huge Halloween bash in Beverly Hills Friday night. Love the costumes!

The trio, wearing their best costumes, also met up with the likes of Rosie Huntington-Whiteley, Alessandra Ambrosio and Julianne's boyfriend Ryan Seacrest at the star-studded event in the hills. If only we could get a peek at what Ryan was wearing!

Derek Hough and his adorable pooch went for a jog this morning, but rather than wearing gym shorts and a tee, the Dancing With The Stars hottie rocked a pair of fitted red pants and showed off his toned abs!

While this may not be the most practical exercise outfit, there's no denying that Derek looks pretty sexy in it. Julianne's big brother been dancing nonstop for the new season of DWTS, and he posted a blog earlier today detailing how he tailors his diet to help give him the most energy onstage.

"I’m all about creating healthy eating habits that include foods rich in antioxidants and protein," he writes. So what does he put in his mouth for his first meal of the day? Sausage and protein shakes, along with fruit and the occasional stack of pancakes. Yum!

Derek Hough's one cool uncle!

Yesterday, cameras caught the Dancing With The Stars hunk doing some shopping with one of his sisters and her son in Beverly Hills. A family that shops together, stays together!

The dancing pro let fans in on his plans when he tweeted, "Where can I find really cool hip clothes for 7yr old boy in Hollywood?" He then seemed to have found a good starting point when he followed with, "Pimpin out my nephew with some new Creative Recreations. Now we got to get him a new outfit for the MTV music awards."

Derek's been hanging tough since missing out on the DWTS finale but he seems to have moved on past that and has his eyes set for the MTV Movie Awards (the music awards are in September Derek!) this weekend. Wonder if he's still thinking about his former dance partner Maria Menounos?
