Rapper/reality star Shad "Bow Wow" Moss is making some shocking allegations, against R Kelly's ex-wife Andrea Kelly. According to Bow Wow, Andrea "lied on him."

Bow Wow is close friends with R Kelly, and he's been a staunch defender of the disgraced R&B singer. And Bow Wow will make his feelings known tonight - on the WEtv show Growing Up Hip Hop LA.

In tonight's episode, Bow Wow will imply that the federal underage rape charges against R Kelly are fraudulent, and brought about by women :lying on him," especially his ex-wife Andrea.

Andrea remained silent about her ex-husband's abuse allegations, until R Kelly defaulted on his $20,000 per month child support  payments. Then she went public, alleging abuse during their marriage and claiming that she suspected  R Kelly was having relationships with underage girls.

Under terms of his 2009 divorce, R Kelly had been ordered to pay more than $20,000 a month in child support, but stopped making the required payments last year. He had been seeking to have those payments reduced, because he is not working.

But before his payments could be reduced, R Kelly was arrested on federal child sex trafficking charges.

In tonight's episode of Growing Up Hip Hop, Bow Wow will accuse Andrea of lying on his friend - and then publicly disrespect her - by curving her at an event.
