Counting down the days! Khloé Kardashian opened up about her brother, Rob Kardashian, becoming a dad during an appearance on Jimmy Kimmel Live! on Thursday, November 3. Hear what she said in the clip above!

"Rob has so many traits like my dad, so I think he's gonna be great with a baby," Khloé, 32, told host Jimmy Kimmel. "I'm sure he's nervous, I think any new dad should be."

The Arthur George sock designer, 29, and his fiancée, Blac Chyna, confirmed in May that they were expecting their first child together. The couple are having a baby girl and plan to televise the birth.

"Chyna keeps going, 'Are you ready? We're having a baby!'" the Strong Looks Better Naked author said on Thursday. "But we meaning, her and I. And I'm like, 'Ah yes,' laughing it off, and now I'm beginning to think no, she's really serious, like it's really her and I."

Hours earlier, Khloé was actually hanging out with Rob and their sister Kourtney Kardashian. The trio toughed it out during a grueling workout, which they documented on Snapchat. They did several exercises together, including weights training and squats.

"Back at it," Khloé captioned one pic. Kourtney, 37, added in a video: "Today's torture."

Back in April, Rob revealed via Instagram that he wants to lose more weight. He weighed 248.4 pounds at the time, and hopes to reach his goal of 200 to 205 pounds.
