The 2013 Teen Choice Awards was a family affair for Miley Cyrus. The 20-year-old "We Can't Stop" singer attended the award show at the Gibson Amphitheatre in Universal City, Calif. on Aug. 11, with sister Noah Cyrus and dad Billy Ray Cyrus.

To help her accept her award for Choice TV Scene Stealer, Choice Summer song and Candie's Fashion Trendsetter, Miley brought her 13-year-old teen sister, Noah, up on stage with her. For the TCAs, Miley wore an ultra black leather miniskirt by Yves Saint Laurent with a fishnet shirt that exposed her black leather bra underneath. She accessorized the look with sky-high white platform pumps.

Her teen sister, meanwhile, took the stage in a much more casual ensemble. Noah, who must have gotten chilly during the show, wore her dad's gray zip-up hoodie over a black shirt and shorts. The sweatshirt was so big on her, that it made it look like she was wearing no pants underneath.

Miley told her fans on stage, "To be a trendsetter, you have to have an amazing group of people to follow your trends. I encourage you guys to always be different." Last month, Noah told Us Weekly that Miley gives her style advice. "She comes to my house a lot and she'll go in my closet," she told Us, "and tell me what things I should keep and what things I shouldn't keep."

Miley and Noah posed together in the audience with dad Billy Ray, 51, during the show. The family showed a united front after their parents called off their divorce plans. After going to couples therapy, the spouses of 19 years decided they wanted to stay together.

Tish Cyrus initially filed for divorce on June 13. That same day, Noah tweeted, "Please pray for me and my family. Xxo."
