SOULJA BOY is claiming that Chris Brown has pulled out of their celebrity boxing match.

    The pair have been involved in a feud on social media and had arranged to fight in Las Vegas over three rounds but a date was never announced.

    Former heavyweight champion Mike Tyson was training Brown while Boy was being put through his paces by another boxing star Floyd Mayweather.

    But the rapper has tweeted to say the US$1m grudge fight is off.

    “Chris Brown’s manager called my manager last night and said the fight is off and he’s not signing contract. Don’t ask me about [it] no more.

    “I aint gon say ... he shook or nothing. I’m just gon say he don’t wanna fight. simple. I can’t force him to sign the [contract].”

    The grudge started after Boy liked and left a comment below a picture on the profile of Karrueche Tran, Brown’s ex-girlfriend.

    The pair posted several videos and pictures mocking and threatening each other as the argument heated up.

    Brown, 27, and Boy, 26, have been criticized by fans and other celebrities for their public feud. Boy has been accused of using the match as a tactic to boost his music career. (SD-Agencies)
