He’s turning over a new leaf! Rob Kardashian is living a healthier lifestyle and even making amends with his famous family — and it’s all thanks to his new girlfriend, Blac Chyna, an insider tells Us Weekly.

“Everything about him has changed,” a friend of Rob’s tells Us. “She’s been so good for him. He says he can’t believe a girl this hot is into him.”

The pair showed some cute PDA (including an impressive handshake!) during Chyna’s beachside photo shoot for alkaline water company 138 Water on Thursday, February 4, and have been unafraid to show their affection for one another since going public with their romance last month.

The reclusive reality star, 28, was spotted looking happy and carefree as he watched Chyna, 27, flaunt her figure in a tiny two-piece swimsuit and later, go completely topless.

Their burgeoning romance has had other positive impacts as well — including a better relationship with his mom, Kris Jenner, and family.

“He’s changed so much, that’s why he was able to talk to his mom,” the source adds. “They reconnected and had a long talk. I think Kris is so happy he’s finally out of his shell, so if it took Blac Chyna to get him here, so be it.”

On Wednesday, Rob posted a photo of Kris’ hand clutching her sunglasses, with the caption “Hey pretty mama” and several heart-eye emojis.

And on Friday, February 5, Rob held onto his baby nephew Saint during sister Kim’s livestream.

Khloé Kardashian’s BFF, Malika Haqq, also told Us that she thinks the Kardashians will stand by Rob no matter what.

“They’re a family that’s always supportive,” she told Us at the NAACP Image Awards on Friday, February 5. “They can fight like cats and dogs but nobody else can fight with them. They can do that with each other and keep it movin’.”
