Robert Kardashian can't stop beaming ever since he got engaged to Blac Chyna. Not just that, he can't help sharing all the loved-up moments with Instagram followers. In his recent picture on Instagram, Rob Kardashian can be seen with Blac Chyna's teeth whitening kit. And you can even get a discount if you enter the code "Rob" at checkout. Blac Chyna really does know how to do business, doesn't she?

The picture is accompanied with a caption that informs the fans about the offer.

"Getting my grill right with my @expresssmileatlanta teeth whitening kit. Thanks, babe @blacchyna for putting me on!???? Enter code: Rob at checkout to get yours for $20 today! That'll Teach Em!"

Rob Kardashian is a nice boyfriend after all, isn't he? But one wonders what Blac Chyna's intent here is. Do you think Blac Chyna might just be using the Kardashian brand name to sell her products? That's quite possible, given the intense competition she has with Kylie Lip Kits. This is not the first time Rob Kardashian has unofficially helped Blac Chyna with her business ventures. She can often be seen igniting a war with Kylie Jenner, who, one would believe, is Blac Chyna's rival with a cosmetic line of her own.

The Inquisitr previously reported that Blac Chyna and Kylie Jenner can be seen engaging in a regular Instagram war, and if there is one person who is backing it all up, it's Rob Kardashian. Blac Chyna and Kylie Jenner can literally be seen posting the same kind of pics, but there is someone else who is mimicking the behavior: Rob Kardashian. Do you think Rob Kardashian has finally let his family go just so he can be with Blac Chyna? That's possible.

There have also been several other signs and reports that point to the fact that Blac Chyna might just have forced Rob Kardashian into engagement. TMZ reported that many of Rob Kardashian's friends think Blac Chyna might just be preying on him. And it looks like Rob's family is of the same view. Kylie Jenner, Rob's half-sister and Tyga's girlfriend (Tyga is Blac Chyna's ex and has a 3-year-old kid with her), thinks Rob Kardashian is in need of some serious therapy, Hollywood Life has reported.

"Kylie's going through it with her brother and wants the family to immediately get him into some therapy," a source said.

The magazine has also stated that Tyga has been very supportive.

"Tyga's being very supportive as Kylie and her emotions are all over the place," the source said.

Do you think Rob Kardashian should open his eyes sooner than later to realize that all is not well?

It was the Hollywood Gossip that suggested Blac Chyna has probably forced Rob Kardashian to propose to her. And the Inquisitr reported that Rob Kardashian and Blac Chyna have not officially been congratulated by the Kardashian clan.

However, Tyga, Blac Chyna's ex, seems to have said something about the engagement on Twitter, and the gist of his tweets is that he just wants to see Blac Chyna happy. Don't we all?

Tyga, Kylie Jenner's boyfriend, said, "It makes me happy to see the mother of my son happy. My only concern in this situation is my son. I want him in happy environments."

Seems like Tyga's first priority is the kid, obviously.

What does Blac Chyna have to say about the absence of Kardashian family's reaction to the engagement? If reports are to be believed, "Blac Chyna is very hurt that [Rob Kardashian's] family hasn't even congratulated them, she was hoping that when they saw how serious Rob and she are that it would change things. But nothing has changed, they're still acting like they're too good for her," an insider told Hollywood Life.
