And if Khlo wasn't already hitched, she tells us why she would want to be the one to date Rihanna!
"I would love my brother Rob to go out on a date with Rihanna," Khlo tells us. "She is a strong, confident woman, and I definitely think he would have a blast on a grown-up date."
Just a few weeks ago, Khlo told us that Rob needed to grow up and stop dating "disgusting little tramps." Her words, not ours, Rob.
But if it doesn't work out between Robianna, Khlo says, "Shoot, I will date her LOL."
Whether on Khloé's arm or Rob's, we would love to see Ri making appearances on the next season of Keeping Up With the Kardashians!
We already know Rob loves Rihanna's music (and even sings along), and as we told you this week, the lone Kardashian male has always had a thing for sexy songstresses and just entered the music biz himself.
And it appears Rob would be totally into letting his big sis set him up. We even caught Rob flirting with Ri over Twitter (twirting?) this week. When she tweeted about performing in London, Rob replied back to her, "West Coast!"
Looks like these two need to line up their travel schedules ASAP and set up a real date. And yes, Khloé, you can chaperone.
