Blac Chyna is a positive influence on Rob Kardashian.
The reclusive reality TV star's relationship with the model has caused shockwaves among his family, who are said to be furious about their romance, but Blac's close friend Amber Rose insists she is perfect for Rob.
Speaking on the 'Allegedly' podcast with Theo Von and Matthew Cole Weiss, she said: "I think if people are happy then that's what's most important. Period. They're working out. Chyna is cooking healthy meals for him. It's a really, really good vibe."
Rob has removed himself from public life in recent years as his weight has ballooned and Amber thinks it is a pity that he has become so reclusive.
She said: "Man Rob is the coolest guy you'll ever meet in your life. He's realistic, you know. He's an amazing person. And it's sad that people don't really get to see that. He's just down to earth... and just, just cool. Like he gets life. He gets it."
Rob's family are upset about the relationship because Blac has been engaged in a long-running feud with his younger sister Kylie Jenner.
Kylie and Blac - who used to be Kim Kardashian West's best friend - fell out after Kylie started dating Blac's ex-fiance Tyga, who is the father of her three-year-old son King Cairo.
