The 25-year-old musician regrets his actions and accepts that he should not disclose his personal life on social media platforms, reported Contactmusic.
"Being young and dumb is one of my strong suits and emotional at best. I love hard and react impulsively when I'm hurt at times. I don't think social media is a place to air out or hash out personal problems.
"So I AM APOLOGIZING I live in a glass house and that makes me great also is my curse. Everybody know I love that girl. I don't care how my image my look to the public because I'm still gonna be the best at what I do. I just want baby girl to know I apologise!," said the 'With You' hitmaker.
"I did not delete my Instagram. I'm way too addicted. Soomeone reported my page as an impersonation and now it's disabled," she posted on Twitter.
Brown and Tran dated on-and-off over the past few years and they split again last week.
