Brandi Cyrus rocked the CMT Awards red carpet. Miley Cyrus' big sister went for a sheer dress that showed the singer isn't the only star in the Cyrus family sky, reported E News.

Accompanied by dad Billy Ray, Brandi showed her CMT sizzle by choosing a desert-themed cactus and flower accented dress. The nearly-see-through choice revealed that the 28-year-old has nothing to hide when it comes to her fabulous figure.

The Cyrus patriarch decided to demonstrate his denim delight for the CMT fans, but included a flash of leather in his jacket choice. Apparently he's Still the King.

In addition to Brandi and her studly father, Cyrus, the CMT Awards 2015 stood out because of Carrie Underwood's post-baby body beauty. And everyone wanted to know just how Underwood restored her pre-baby body so quickly, reported E News.

Carrie underwent a C-section, which made it challenging to achieve her weight loss goals. But despite that exercise restriction, she appeared at the CMT Awards in a mini dress only three months after the birth of Isaiah Michael Fisher.

Underwood revealed that she was careful to eat right and exercise during her pregnancy.

"While I was pregnant, I did everything I could to try and make smart choices," Carrie revealed. "And if I couldn't really like work out, work out, I'd go walk, and I just tried to stay active."

After the baby was born, the cesarean made Underwood decide to rely on dietary changes to achieve her desired weight loss before the CMT Awards.

"[I] kind of alter(ed) my diet," explained Carrie.

As for her diet specifics, Underwood is a vegan, as the Inquistr reported. During her pregnancy, Carrie temporarily shifted to a vegetarian food plan, then returned to her vegan diet after the baby was born.

Initially a vegetarian, Carrie revealed that a friend's success on a vegan diet encouraged her, reported Self.

"After seeing a friend who looked amazing and had recently gone vegan, I thought, 'What's holding me back?' Now I'm 95 percent vegan," Underwood revealed.

Carrie also expressed concern about the source of her food, seeking to eat clean. She noted that is part of the reason that she's become a vegan.

"My veganism is based on a concern about where my food is coming from. In my perfect world, I'd have webcams wherever food is processed so I'd know how clean it is," added Underwood.
