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

The 20-year-old singer, who assaulted his on/off girlfriend in February and was recently sentenced to five years probation and six months community labor, has romantically reached out to the “Umbrella” signer 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, Chris posted a link to a version of his new song “Changed Man” on YouTube, which features a series of pictures of him and Rihanna together. Among the photographs are several of the couple, who dated for around 18 months, kissing and cuddling, and others of them laughing and whispering to each other.

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

Chris debuted “Changed Man” in August, and speculation is rife that the track is his attempt to show Rihanna just how sorry he is for the attack.

The lyrics include: “Daily / I’ve been waiting / For the time to pass / and let it fade in / They looking at you / Telling you / We need to break it up / 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.”

Chris punched, kicked, and choked Rihanna in his rented silver Lamborghini in February after attending a pre-Grammy party. After the incident the pair went on a make-or-break holiday to Miami together, but have not been seen with each other since. He received his sentence in August and was left distraught when the judge banned him from contacting or seeing Rihanna for five years.

He has admitted being ashamed of what happened during an interview and confessed that he would struggle to cope if Rihanna found love with a new man.
