Rob Kardashian and Blac Chyna have one thing going for them: their marriage can't be any worse than Khloe Kardashian and Lamar Odom's.
In a sneak peek clip at Sunday's new episode of "Keeping Up with the Kardashians," the exes talk about Rob's surprise engagement in a pretty light-hearted chat. We gotta say, it's great to see them looking so happy and relaxed with each other, despite their split and all the drama Odom went through last year.
"Is Robert Arthur Kardashian getting married?" the basketball star asks Khloe at the top of the video.
"He says he's getting married. I don't know when, he doesn't tell us anything," Kardashian responds, showing her frustrations with her brother. "Rob has disconnected himself from us, apparently mainly me, I hear he talks to my sisters way more."
"I hope he's focused," Lamar then says. "Marriage ain't easy honey child."
Khloe, clearly knowing he speaks the truth from her own personal experience, laughs ... before asking him, "It's not? Your marriage wasn't easy?"
The two then decide to give Rob a phone call -- and Khloe is absolutely shocked when he actually answers.
In case you missed last week's episode, Rob finally broke the pregnancy news to his sisters, and Khloe did not take it well. Since then, it appears the two have not been speaking to each other.
"It does make me smile because at least I know he's finally going to answer my phone calls," Kardashian admits in a confessional.
But as Lamar and Rob make plans to grab dinner without her, she can't help but feel a little slighted.
"I have always loved Lamar and Rob's relationship and bond and I want them to hang out," she says. "[But] I want my time with Rob, he hasn't had any one on one time with me. Rob hasn't attempted to do anything with me."
While they all clearly went through a rough patch, it seems like the family has since mended fences. Rob and Blac Chyna were both on hand at Khloe's birthday bash last week.
