Rob Kardashian never actually said Rita Ora's name in the Twitter rant, but it was pretty obvious to any Kardashian-watcher what was going on. He has since taken down the tweets, but not before a number of Twitter users grabbed screenshots of the whole tirade.

Plus, Rob's older sister, Khloe Kardashian Odom, tweeted a supportive message that only backs up that assertion: “Cheaters never prosper @RobKardashian ill be home today... Try and smile little brother.”

The fact that the cheating allegation is just an empty claim so far and Rita Ora's name didn't come up in any of the tweets didn't stop the Web from taking the rumors and running with them, and "Rita Whora" went on to trend heavily nationally on Twitter.

Twitter user @AwlinFerrier stoked the flames with his own nicknames for the singer with the following tweet:

“Cheater Ora, Rita Oral, Rita Whora. There's twenty more where that came from.”

However, some of the tweets instead threw dirt at the Kardashians, including this one by @SmileyBeliebz:

“Rita Whora? lol Rob Kardashian, I think you got Rita mixed up with your sisters.”

It seems controversy is never far away, no matter which member of the Kardashian clan is in the spotlight.
