And Kim Kardashian got straight to the point during a lunch in Malibu as she questioned if Addison Rae was ‘hooking up’ with her older sister during a sneak peek clip of the latest episode of Keeping Up With The Kardashians.

‘We all decided to get to the bottom of Kourtney and Addison, so we invited Addison over for lunch, but without Kourtney cause we just want to ask a couple of questions and get to know her more,’ Khloe said.

‘We just want to feel her out a little bit,’ Kim assured the cameras during a confessional.

The family — including Kris Jenner, Kendall, Scott Disick and Corey Gamble dives into a series of questions during an opulent outdoor lunch in Malibu and asks Addison where she’s from, if she’s been arrested, her blood type and credit score.

‘Honestly, at the beginning we were like, “Wait are they hooking up?” Cause it was like that kind of relationship,’ Kim told Addison.

‘I’m still thinking that,’ Scott said. ‘That was the elephant in the room. It’s ok if you are. Nobody judges.’

Addison assured the reality stars that she was not, in fact, in a romantic relationship with Kourtney.
