Aaron Carter says he is taking his ex to court for defamation, declaring the case will turn into "Amber Heard Johnny Depp 2.0".
The singer and former child star, 34, even issued a plea to Camille Vasquez, who represented Johnny in the shocking US defamation case, to help him.
Aaron said he intends to sue his on-off girlfriend Melanie Martin for defamation after she accused him of breaking her ribs, which he denies, and says the claims nearly cost him his career.
