WASHINGTON - Rob Kardashian is reportedly worried his fiancée Blac Chyna will cheat on him and is “very insecure in their relationship”.

The Keeping Up With The Kardashians star - who is expecting a baby with Chyna - is reportedly suffering from trust issues when it comes to their relationship.

A source told _People _magazine: “He is very insecure in his relationship with Chyna.

“They’ve had many instances and fights in which he accuses or suspects that she’s cheated. His issues with trusting girlfriends are deep-rooted.”

Meanwhile, the 29-year-old television personality is also insecure about his weight.

He confessed recently: “I do not want to go to Cannes anyways. Even when I was in the best shape of my entire life, I still had an insecurity with my weight.

“On top of that, there’s paparazzi people that follow me and take pictures of me and that shuts me down to not wanting to go out when I’m obviously not feeling my best. I’m not comfortable in my skin, I’m not comfortable with this weight. So I feel like I’m not happy with anything I do right now.”

However, Rob’s mother Kris Jenner is confident that her son will be able to put his weight troubles behind him.

She shared: “Any time you get down on yourself, it’s always a process to get back on top of it. And Rob has always been so athletic, he was the star track guy in high school and a basketball player, and he was the runner up after 20-whatever weeks on Dancing With the Stars, and dancing live in front of 40 million people or whatever it was...

“He’s been such an amazing athlete and in such great shape and very athletic his whole life, so this is not in his comfort zone. This isn’t something he’s experienced, so it’s hard. It’s hard for him to get the weight off like it is for any of us, so he’s definitely been challenged by this. He’ll work through it. I really have faith in him. He’s just gotta put his mind to it.”
