The model is said to be livid after Chris posted a candid video he has named 'The Real Chris Brown' onto his twitter page last Thursday (04.10.12) during which he discusses his romantic dilemma over the two women.
Karrueche can't believe the R&B singer shared their personal problems all over the internet, according to US gossip website TMZ.
A source said she wishes he had kept his feelings private and is disappointed and hurt by his decision to broadcast why they split.
The 'Yeah 3x' hitmaker dumped his model girlfriend of more than one year last week because he said he couldn't give up his ''friendship'' with his ex Rihanna - who he was convicted of assaulting in 2009 - and friends of Chris say he wants to put things right with the 'We Found Love' singer.
He later posted the professionally produced video in which he is seen with his arms around Rihanna in a nightclub intermixed with images of Karrueche.
During the footage he said: ''I'm stressed out ... when you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult.
''Is there such thing as loving two people? I don't know if that's possible, but for me, I feel like that.''
