So we have all seen and heard about Kendall Jenner and Harry Styles enjoying their first dinner date ever in West Hollywood, Los Angeles last month, and their recent private rendezvous in London last weekend after the One Direction member quickly flew back from an awards ceremony in France to spend time with his new love interest. Now, the Keeping Up with the Kardashians reality star's half-brother Brody Jenner has something to say about the pair's publicized romance.

Brody Jenner has warned the British cutie that his 18-year-old sister will break his heart because all she wants to do is to just have fun, and she is definitely not ready to commit in a serious relationship.

"I hate to tell you this, but Kendall will be doing the heartbreaking," says Jenner. "I'm sure she's having a fun time with him. She has a very level head, great head on her shoulders. But they are both so young."

"She is at that age where dating is a lot of fun," he adds.

In addition, although Brody Jenner does not think that the couple's romantic relationship will last forever, he has expressed that he is still happy for his sister. He also has revealed that their father Bruce Jenner has approved Kendall dating the 19-year-old pop sensation.

"It sounds like a match made in heaven," he says. "That's what it sounds like, but I've never met him. My dad told me that Harry Styles plays golf, so that's cool."
