And you thought Rihanna was fierce in the "Man Down" video! The singer sounded seriously fired up at MTV Canada today for a story the site ran based on a tweet the singer supposedly wrote regarding Chris Brown and the night he beat her up. The problem is, she says that tweet wasn't from her. So what happened? RiRi slammed the cable network for an article quoting a tweet claiming she'd "provoked" Chris Brown the night he beat her. The tweet read, "'I admit it. I provoked Chris [Brown] to hit me. It's not entirely his fault. #imSORRY?' " The singer (the real one this time, apparently) tweeted this response: "are u f--king kiddin me?????? You're supposed to be a RELIABLE source for news on music and this is the bulls--t u post??" A chastened MTV Canada tweeted later, "Rihanna fans. We were reporting on a story that was posted on several sites today. We had no intention to be salacious." Chris Brown was also causing a stir on Twitter today, though on an entirely different topic. The singer was apologizing to the gay community for tweeting, "Y'all n---as is weak. Did you call them to try and film me? Y'all n---as is gay!" After an outcry, he responded, "I have total respect for Gay community and my intention was not to insult anyone in it." But soon enough he was back to complaining about how he was being treated by others. "Latching on to my every word and criticizing makes you look thirsty. I can't even piss without somebody complaining. Imagine how I feel," he wrote later. Imagine how you feel? Why, we have your tweets to tell us! Source: E! Online
