In a now-deleted Instagram post, Tamar accused her estranged husband of cheating on her with a woman who is believed to be Basketball Wives LA star Laura Govan and she even claimed that Vince got Laura pregnant.
Braxton and Herbert split in October after nearly nine years of marriage.
The Braxton Family Values star, 40, captioned the message: "Say what you was about me...but I'm good & Got Damn exhausted of the bull 2018 belongs to who DARES to take your life BACK!" She added that she has never been with Vincent AND she's not pregnant right now.
Govan also blames her ex-husband, Gilbert Arenas, for spreading falsehoods online, which may explain the confusion.More news: Are the Bucs making the right move by sticking with Dirk Koetter?
"We might need to tear down your vagina and build you a new vagina", he wrote.
And she said Melissa was ungrateful, as Herbert, who worked with Dream on their first album, helped them sell "millions of records". This is consistent with Fameolous' reporting that Gilbert claims to have seen the pair together on vacation and chose to tell Tamar about it. I have no issues towards Tamar or Vince, because I know who actually started all of this. Then, it was revealed that Vincent had been arrested on Christmas day, reportedly for spousal assault.
"While celebrating the Christmas holiday as a family, after a few drinks and some jealousy, things got a bit out of hand", Tamar said to TMZ.
However Tamar lashed out at Melissa, saying the comic and singer was using her "personal family situation" with Vincent to get "attention". He was ultimately released the same day on $20,000 bond.
In the past, Braxton's mother, Evelyn, has said that Herbert has physically abused her daughter.
