French Montana is totally on board Rob Kardashian's much-panned relationship with Blac Chyna. The rapper says Rob is in much better place after he starts dating Chyna despite her history with the Kardashian family.

"I love the energy that Rob is in. That's my little brother. But I love him. So I love the energy he's in," Montana said at the premiere of his debut film "The Perfect Match". He added, "As long as somebody is happy doing what they're doing and working out, having a lot of energy, I love that. It's the best years of his life, why would you stop that?"

Rob has been facing criticism from his family, especially sister Khloe Kardashian who said, "God knows who the f**k he listens to at this point," earlier this month. The relationship is causing tension between the family members because Chyna is the baby mama of Kylie Jenner's on-/off-boyfriend Tyga as well as Kim Kardashian's former BFF.

Montana, who used to date Khloe, believes that relationship can be complicated. "Ain't that every relationship in Hollywood?" he said about Rob and Chyna's. "I feel like there's no perfect match out there. I feel like guys and girls go into relationships with a perfect match in their mind. They don't get to know the person. So I think the perfect match is when you get with somebody and accept them for who they are and mold them to be someone you love."

Rob was at Los Angeles International Airport on Tuesday, March 8. He was diagnosed with diabetes in December last year. He reportedly has lost 40 lbs. since Chyna put him into healthy diet regime. "He has really good energy and every time I speak to him he's working out or doing something positive. I love that," Montana quipped.
