Rob Kardashian claimed that the cheating woman he recently meant on his tweets was not Rita Ora. Following speculation that his Twitter rant was directed at his ex-girlfriend, he insisted that he never mentioned the singer's name.

"Just so we clear I never once mentioned 'Rita Ora' in any of my tweets or even used the word 'whore' and I never would. I Respect Women," Rob tweeted. "Sad that the media created negativity for a young artist new to the game that is working so hard to make it. Never mentioned any names."

"I speak truth. I'm a very Real dude and everything I say I mean... But never called anyone specific a whore and said any names. You all did," he explained. The tweets have been removed from his account.

The only son of Robert Kardashian and Kris Jenner launched a Twitter rant on Monday morning, December 3 to an ex-girlfriend, who was rumored to be the British singer. He said, "She cheated on me with nearly 20 dudes while we were together."

He then added, "I wonder how many she will sleep with now that we apart? But I mean 20?!!!" The "Keeping Up with the Kardashians" star quickly deleted the tweets.

On Tuesday, December 4, a tweet using the name Rita was circulating. It read, "Rob's d**k was wack, I had to go get it somewhere else." Rob allegedly tweeted back, "So you let me get you pregnant and you let others hit raw?"

However, Rob has said that both tweets were fake. He tweeted to Perez Hilton which brought the faux tweets into attention, "@PerezHilton Don't see why you'd bring so much negativity to PHOTOSHOPPED tweets considering she is your friend. You should know better."

Rob and Rita were first romantically linked in July. They sparked more dating rumor by sharing a picture, which features them looking intimate together. According to a source, the couple ended their relationship in November because of the long distance between them.

Rita recently opened up to Glamour U.K. about why she split from the Kardashian boy. She said, "I'm not going out with Rob. We were close for a while, but it didn't work because I was never there. I was like a ghost."

She went on, "I used to get so frustrated with myself and then wonder why I was angry, so I decided it was best to keep it friendly..." She then added, "Especially at the moment, when there's so much going on."

She then revealed that she had a problem with commitment, "I think it's my only weakness." She continued, "I'm scared of letting my guard down, and if I feel in love with someone now, he'd have to try ten times harder to break it down."
