Rob's Family Fear Alexis Skyy Relationship Will End In Disaster: 'She's Using Him!'

Blac Chyna isn't the only one upset about Rob Kardashian's new romance with nemesis Alexis Skyy, as RadarOnline.com has exclusively learned that his famous family is afraid the relationship will end in disaster!

"Rob's sisters are hopeful that things will work out between Rob and Alexis, but none of them think that it will at all," an insider said.

"They all really believe that Rob is using this girl to get back and Blac Chyna, a claim that he doesn't deny. They have told Rob to keep his romance out of the spotlight or it will fail, but Rob isn't listening to their advice."

According to the pal, Rob's twisted sisters Kim, 38, Kourtney, 39, and Khloe Kardashian, 34, think that Alexis is just after the Koveted Kardashian sperm!

"Alexis would give anything to get pregnant with Rob's baby. She has even been telling people that and Rob's sisters think it is just gross," the source told RadarOnline.com.

But after declaring online that she was "in love" with the overweight 31-year-old, Skyy, 24 — who already has one child with rapper Fetty Wap, 27 — has been at war with Rob's ex Blac Chyna, 27, on social media!

On January 22, Blac Chyna slammed Rob and Skyy's new relationship — insisting that she would never even get to meet their daughter because of a clause that Rob and Blac Chyna put in place in their divorce agreement that is meant to prevent their daughter from getting attached to in-and-out lovers.

Meanwhile, there is one family member supportive of her son's new gal pal — money-hungry momager, Kris Jenner, 63!

"Kris is loving every single minute of this drama because she knows that it will make for some great TV next season when Rob returns," the insider added.
