Kim Kardashian-West channeled her inner pin-up girl for a racy Rolling Stone cover shot by famed photographer Terry Richardson that was released on Wednesday.

The cover shows Kim sporting some major cleavage in a tight red bra and striped shirt. Inside the issue Kim opens up about her life, career and family, including step-parent Caitlyn Jenner and brother, Rob.

The 34-year-old revealed she caught Jenner cross-dressing when she was 22 years old, 12 years before the announcement was made to the world.

"I didn't know if I'd just found out his deepest, darkest secret and he was going to come after me," Kim said.

Kardashian revealed she was worried about Bruce walking her down the aisle at her 2014 wedding because she was aware Jenner was making some serious changes.

"He had just had his trachea shaved, so I knew something was going on," she said.

In the interview, Kardashian said that her husband helped her with her concerns.

"(Kanye) obviously moves to his own drum," she added. "He lives his life the way he wants, a really authentic life, and he was like, 'If you can't be authentic and you can't live your life, what do you have?'"

The "Keeping Up With the Kardashians" star also discussed her brother Rob's recent absence on the show.

"It's not that mysterious, what's happening with Rob," Kardashian said. "He has gained weight. He feels uncomfortable being on the show, and that's OK. Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."
