Rihanna has reportedly insulted Karrueche Tran by calling her a ''chore'' on twitter and friends say she was never concerned about the model's relationship with Chris Brown
The 'Diamonds' singer - who recently reconciled with Chris even though he is still on probation after being convicted of assaulting her in 2009 - is said to have indirectly insulted his ex Karrueche Tran on twitter calling her a ''chore''.
On Friday (19.10.12) she tweeted: ''If you start feeling like a 'chore' to someone, you probably are!''
A source close to the popstar also told HollywoodLife.com that she was never worried about Chris's relationship with the model, whom he dated for one year but dumped earlier this month, blaming his ''friendship'' with Rihanna.
The source said: ''It was bound to happen. You can't stop a girl who's in love. You just can't. [She's] happy about it, but the funny thing is that she never saw Chris' girl as a threat. Really though, Rihanna don't even know her name. She never mentioned her or anything...That girl was a non-factor.''
Friends say the 24-year-old - who will release her new album 'Unapologetic' next month and is rumoured to be preparing to go public with her relationship shortly afterwards - is happier and more confident since she reunited with Chris.
A friend close to the singer said: ''I know it's a lot easier for her to concentrate and work hard now that Chris is back in her life.
''She don't worry about the bulls**t no more. She don't wonder about what he's doing or who he's with. It's like she feels more secure and confident when he's in her life.''
