TMZKarrueche Tran has not only called it quits with Chris Brown, she has also solidified the break up by changing her phone number. 

Although Tran claims that Chris Brown has played the Rihanna card one too many times, she also told sources he acts "immature, like a child" and that he is spending too much time partying and not enough time making music. 

Breezy allegedly took one of Trans' good friends to St. Tropez this week and made it a point to take a picture with her in hopes that Trans would see it. Trans expressed no jealousy but instead changed her phone number so that Chris could not contact her.
