Kanye West positive about Rob Kardashian's engagement to Blac Chyna

Rapper Kanye West has nothing but positive things to say about Rob Kardashian's engagement to Blac Chyna.

The Famous hitmaker is married to Rob's older sister Kim Kardashian, and when the musician was asked to share his thoughts on his brother-in-law's recent proposal to the glamour model, he couldn't stop smiling.

"Rob is my brother; I love Rob," Kanye told X17 photographers while walking through Los Angeles International Airport (LAX) on Friday (08Apr16). "I just roll with it. I love Rob, that's all I can say. I love Rob."

However, when the hip-hop star was asked if he will be attending Rob and Blac Chyna's wedding, he replied: "You know what? I haven't been invited!"

Kanye's happy-go-lucky response was nothing compared to how Rob's mother, Kris Jenner, reacted when she was asked about her son's engagement while walking with daughter Kourtney Kardashian in Vail, Colorado on Thursday (07Apr16).

When an Entertainment Tonight journalist asked the 60-year-old matriarch to comment on the upcoming nuptials, she responded with some serious sauciness.

"I think you should stop asking me stupid questions," she snapped.

Blac Chyna went public with Rob's proposal early on Tuesday (05Apr16), announcing their engagement by sharing a photo of the loved-up pair on Instagram.

The Kardashian/Jenner clan have yet to issue a congratulatory message to the couple, and it's claimed most of his relatives are incensed over the news.

"It's the worst betrayal ever, especially since Blac has badmouthed the family so many times," a source told Radar Online. "The family thinks Rob's doing this to p**s everyone off because he's so angry."

"There is now an ultimatum in place to deal with this mess," the insider continued. "He's going to be dropped from the family if he marries her."
