Rob Kardashian, a cast member on "Keeping Up The Kardashians," deleted a series of explosive tweets on Tuesday that he fired off about his reported breakup with singer Rita Ora and her allegedly cheating on him. 

The 25-year-old deleted the tweets he originally posted on Monday and much of his Twitter history before the rant began. The oldest post viewers can see was written on Nov. 29. 

"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? But I mean 20?!!!," Kardashian tweeted on Monday, which has since been deleted. "How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship?!"

He then tweeted further to explain his disappointment.

"When a woman cheats on you with one man I can live with that," he wrote. "People make mistakes, trust me. I have forgiven numerous times...But when a woman disrespects herself by messing with more than 20 men all while being in a relationship with a Faithful man..."

One of Kardashian's older sisters, Khloe Kardashian Odom, tweeted solace to her brother.

"Cheaters never prosper @RobKardashian ill be home today... Try and smile little brother....Rob be nice kiddddd," she tweeted. "Social media is so much drama. Hehehe thank goodness there was no social media when I was younger. Too much drama in the LBC."

After Rob's twitter rants went viral, the hashtag term "Rita Whora" began trending on Twitter, E! News reported. 

A source told British tabloid The Sun that the couple split last week due to work schedules and the long distance between them.

"They'd only decided to go public with the romance a couple of months ago so as not to put any pressure on themselves but they've already split," a source told The Sun. "Rob has now deleted everything on Twitter that reminds him of Rita."
