Sounds like mom Kris Jenner and sister Kim Kardashian have really taken to Rob Kardashian's new boo, model Naza Jafarian — but maybe just because they think she's a big upgrade from Rob's previous flame, pop star Rita Ora!

"Kris and Kim like [Naza] a lot more than Rita, because she’s a lot like them," a source tells HollywoodLife. "They didn’t really like Rita at all."

Apparently, Naza came to Rob's birthday party in Vegas, then spent St. Patrick's Day with him. Most recently the duo hit up London together so that Rob could promote his Arthur George sock line. (We're still waiting for our swag bag, Rob!) While across the pond, they even joined Kris for a dinner date. And mom, son, and new girlfriend even went shopping together the next day.

Glad to hear the family is onboard with this new 'ship. Especially since Rob has Kris's face tattooed on his leg. If there was any animosity between Kris and Naza, the latter would always have the inked depiction of Kris watching her!
