Although he never uses her name, Rob Kardashian appears to have tweeted that his girlfriend, Rita Ora, cheated on him. A lot.

Rob started his slew of tweets Monday and Tuesday by saying he was "disgusted" with the "How We Do" singer and her playgirl ways.

"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart?" he wrote.

The pair have reportedly been dating only a few months. Though they never went public with their romance, they did post photos of themselves being all kinds of cute on Twitter in October, which appeared to confirm the relationship rumors that had been surrounding them since May.

Rob deleted the many posts he had up about the alleged cheating. But he was soon back on, posting tweets such as "When a woman cheats on you with one man I can live with that. People make mistakes, trust me. I have forgiven numerous times."

Rob's big sister Khloe tweeted her support, saying, "Try and smile little brother."

According to the Daily Mail, Rob, 25, was due to celebrate Rita's 22nd birthday in London last week, but Rita had reportedly called things off already.

The Mail's source claims she let the reality star go due to her hectic work schedule and their incompatible jet-setting lifestyles.

Movin' on up

Channing Tatum has announced that he's done with acting. Well, in 2013 at least.

The "Magic Mike" star said he's taking a break from acting next year to focus on finding a project to direct with his production partner.

"By the end of next year, we're going to shut things down and write the first thing that we're going to direct," Channing told the Huffington Post. "We're going to be like, alright, no more acting parts for a minute, let's take a few and really get caring about that section of our career."

Channing, who starred in five movies in 2012, has four more films lined up to come out in 2013.

"I love the steps that I've taken acting-wise," he said. "But I don't want to just keep putting [directing] off for these fun and incredible opportunities."
