Last month Karrueche Tran broke up with Chris Brown after it was revealed that he was the father of a 9-month-old baby girl.

Now insiders claim Chris is heartsick over losing Karrueche and trying everything to win her back, but she is having none of it…

Sources tell TMZ

[Chris Brown has been] blowing up [Karrueche’s] phone and her friend’s phones, but she’s radio silent with him. He’s been so frustrated he’s turned to social media, complimenting her for all to see.

But nothing’s worked and he’s depressed and telling his friends he’s not going to date anyone else and is confident Karrueche will come back to him.
