Chris Brown has publicly pleaded for Rihanna to give him another chance, reports.

The 20-year-old singer — who assaulted his then-girlfriend in February, and was sentenced to five years probation and six months community labour — has reached out to the singer online.

He wrote on Twitter: “MY HEART IS INCOMPLETE... the part that is complete is my love for fans, career, friends, family, God. But I’m missing someone or something (sic).”

To ensure it was clear who he was referring to, Brown posted a link to a YouTube video of his new song Changed Man, which features a series of pictures of him and Rihanna together.

Brown added on Twitter: “Sorry all, just one of those days.”

The lyrics to the song include: “You need to trust what you do / It’s you and me my love / But Ima make it up to you / And show the world / I’m a changed man.”
