Kim Kardashian posted a Snapchat Tuesday, this time of herself rubbing Blac Chyna's baby bump. Her technique is questionable.

The Kardashian clan was in San Diego to celebrate their grandmother MJ's birthday. That's Mary Jo Shannon—Kris Jenner's mother—so all the Kardashian and Jenner ladies were there to celebrate her 82nd birthday. That now includes Blac Chyna, the pregnant fiancée of Rob Kardashian.

Despite a brief report that Rob and Chyna split up, they're still together. And at this point, Rob can never half-heartedly or temporarily break up with Blac Chyna again. Now that Kim rubbed the baby bump, he officially has to stay put forever.
