Rob Kardashian and Blac Chyna News: Just Minutes Since He Got The Ring, Rob Kardashian Popped The Question To Blac Chyna

Rob Kardashian had one glittering engagement with Blac Chyna----and it actually had a starry witness too--the jeweller, Ben Baller.

Kardashian popped the question to Blac Chyna as soon as he got the ring, which took five days to make, but was witnessed by the jeweller when it happened.

Ben Baller sold the rock to Kardashian for $325k, and said that they have been friendly for a long time. He grilled Rob about his final decision to pop the question and get married. He saw it happening in front of his eyes.

It was a strange coincidence that Rob asked when his family was out of town.

But meanwhile, there is one person who is not too happy with the question or the answer. Lamar Odom.

One of his closest friends, Lamar is afraid that Blac is just using Kardashian for her personal 'fame and power.'

Rob and Lamar were once very close, but the friendship dropped after the Khloe-Lamar split. So even though they are not the best of friends, Lamar still feels deeply about his friend.

"Lamar fears for Rob's heart. They haven't been as close as they were in the past, but he is still looking out for his little brother and Lamar thinks Blac may be up to no good. Lamar has warned Rob that Blac may be playing him for fame and power, but Rob is blinded by love and won't listen to anyone that has anything negative to say. Lamar knows better than anyone close to Rob how much broken hearts hurt, so he is trying to save Rob from some of the mistakes he has made in life," a source tells HollywoodLife.com
