A new report revealed why Dawn Robinson was absent from the R & B Divas Live reunion special that aired on Wednesday.

MediaTakeout reported on Thursday that Robinson did not attend because she was hit with a lawsuit for slander by her ex-husband.

Andre Allen, who was married to the En Vogue member for five years, said he filed a petition for a lawsuit against Robinson and TV One network. Allen told MediaTakeout that he is upset that Robinson spoke negatively about him throughout the season.

The website published an excerpt of an email sent to them by Allen. He revealed everyone he named in his lawsuit for what he says are lies made up about him.

"I wanted to personally inform you and the media that I am suing Thinkfactory, TV One, Dawn Robinson, Phil Thornton, and anyone else that has ANYTHING to do with mentioning DAWN'S EX HUSBAND out of their mouth having 3 kids outside of the marriage and beating her," Allen wrote.

"[They] should have done [their] homework. Dawn was the only individual arrested for domestic violence while we were married," he revealed. "And it would be IMPOSSIBLE for my 20, 17, 4 and 2 year olds to have been born during a 5 year marriage that ended 6 years ago."

Allen also claimed that the negative discussions about him played on television have affected his business.

"Two of my clients brought up concerns after watching [the show R&B Divas] and my company nets over $3mil a year collectively from both. DAMAGES! And [they] slandered a man with AMPLE resources so expect a good fight," Allen said. 

While the reunion special aired on television Robinson wrote on Twitter to help explain why she did not attend. She did not mention Allen.

"The reunion show? Like that was my end all BE all FOR REAL???" Robsinson tweeted adding, "I tried 2 keep positive but production WON'T HAVE IT because THEY DON'T GET RATINGS & without RATINGS, they don't get MONEY." 

Robinson released a statement to 4umf.com and said, "That is not what I signed up for! I signed up for positivity."

 TV One will air part 2 of R & B Divas LA Reunion special on Wednesday, Sept. 11
