Answer by taking a quote from the following article:

Christopher Maurice Brown was born on May 5, 1989, in the small town of Tappahannock, Virginia, to Joyce Hawkins, a former day care center director, and Clinton Brown, a corrections officer at a local prison. He has an older sister, Lytrell Bundy, who works in a bank. Music was always present in Brown's life beginning in his childhood. He would listen to soul albums that his parents owned, and eventually began to show interest in the hip-hop scene.

In 2011, Brown began dating aspiring model Karrueche Tran. In October 2012, Brown announced that he ended his relationship with Tran because he did not "want to see her hurt over my friendship with Rihanna." The day after the announcement, Brown released a video entitled "The Real Chris Brown", which features images of himself, Tran, and Rihanna, as Brown wonders, "Is there such thing as loving two people? I don't know if it's possible, but I feel like that."  In January 2013, Rihanna confirmed that she and Brown had resumed their romantic relationship, stating, "It's different now. We don't have those types of arguments anymore. We talk about shit. We value each other. We know exactly what we have now, and we don't want to lose that." Speaking of Brown, Rihanna also said, "He's not the monster everybody thinks. He's a good person. He has a fantastic heart. He's giving and loving. And he's fun to be around. That's what I love about him - he always makes me laugh. All I want to do is laugh, really - and I do that with him." However, she also declared that she would walk away if Brown showed a hint of his past violent behavior towards her again. In a May 2013 interview, Brown stated that he and Rihanna had broken up again. He subsequently reunited with Tran, but they parted ways following confirmation of Brown's daughter with Nia Guzman in 2015.  In February 2017, Tran was granted a temporary 100-yard restraining order against Brown, and eventually a 5-year restraining order against the singer, claiming he threatened to kill her.

Who has he been involved with?
model Karrueche Tran.
