Brody Jenner shared his opinion on his younger sister, Kendall Jenner's, controversial transition into adulthood.

While many people are still talking about Kendall's racy Instagram picture, in which she's wearing a see-through top exposing her breasts, Brody reminded fans to not be so critical of his half-sister because she's 18 and officially a woman. 

"I know there was a lot of controversy about Kendall turning 18 and that picture, but Kendall is a model. At the end of the day, she's 18-year-old woman," Bruce Jenner's son told People magazine in a Saturday, Nov. 23 report. "She's allowed to do whatever she wants and we will support her...She's a model. She's beautiful, look at her. You don't see people say that to Kate Moss."

Brody, 30, continued defending his sister and said many people make negative comments because of Kendall's type of fame, starting with her appearances on Keeping Up With the Kardashians. Brody explained, "Just because Kendall is in the spotlight the way she is, people just say things, but she's allowed to do what she wants and we support her fully." 

He also opened up about how his father is doing since splitting from Kris Jenner. 

"He's great. I tend to stay away from that because he's my dad. He's my family, so I don't read the press or the media, you know, I just talked to him personally. As far as I know, he's great."

Brody, who was a reality star himself on MTV's hit show The Hills, revealed that there's one topic the father and son always discuss when they catch up. 

"It's all about golf; all we talk about is golf," he said. "We talk all the time. We talked this morning."

Bruce's step-daughter, Khloe Kardashian, also recently revealed that her parent's separation isn't much of a surprise. She said Bruce and her mother have lived in separate houses for about a year, and that the breakup has helped them get along better.

"They're nicer to each other now," she explained. "My mom could get frustrated with him very quickly. Or he would always want to play golf and be gone...I even said on the show, 'Once you guys put that much space in between you guys, I don't think you will ever move back together.' "
