Rob Kardashian is making Khloe Kardashian "smile" this Sunday.
On the next episode of Keeping Up With the Kardashians, Khloe tells Lamar Odom that Rob has "disconnected" from her after getting engaged to Blac Chyna and revealing she's pregnant with his child.
"Call Rob," Lamar says.
"I mean he probably won't answer my phone call," Khloe tells Lamar. "Do you wanna try?"
The two then FaceTime Rob from Khloe's phone and to her surprise, he answers.
"I am really surprised that Rob answered the call because even though Lamar's calling him it's from my phone," Khloe explains. "It does make me smile because at least I know he's finally gonna answer one of my phone calls."
Even though Rob answered the phone call, Khloe doesn't say anything to Rob during the call and Lamar does all the talking.
"You getting married soon daddio?" Lamar asks.
"Yeah—I don't know how soon but first comes love then comes marriage, you know," Rob tells Lamar.
Lamar and Rob make plans to see each other later in the week and Khloe admits she wants to spend time with Rob.
"I have always loved Lamar and Rob's relationship and bond and I want them to hang out but you know I still want my time with Rob," Khloe says. "He hasn't had any one-on-one time with me, Rob hasn't attempted to do anything with me."
