Tamar Braxton slammed by fiancé’s baby mother

Tamar Braxton is celebrating her 46th birthday with a side of drama.

The “All the Way Home” singer took to Instagram to commemorate her big day on Friday, penning a sweet message to her fiancé, Jeremy “JR” Robinson, for keeping a “cheesy smile” on her face.

In the post, Braxton — who shares son Logan, 9, with ex-husband Vincent Herbert — also noted that she and Robinson’s blended family has a total of six children.

“So miss me with the he has 4 baby mamas!!” she wrote. “Thank God for them. We are blessed And drama free.”

One of Robinson’s baby mamas Anaston Jeni got wind of Braxton’s remarks and slammed the singer for not being “honest” about her relationship with his children and their mothers.

“I have sat in silence for over a year, respecting everyone’s privacy while they disrespected mine,” she wrote on Instagram Friday. “I’ve sat in silence while this person has come into my son’s life and caused nothing but chaos and unnecessary drama.”

Jeni clarified that the “Braxton Family Values” alum was “in no way a bonus or step mom” to her and Robinson’s son, Asher.

“My son does not mean ‘everything’ to her and she has not thanked God for me & truthfully, none of his baby mamas,” she continued, adding that Braxton has said “demeaning, disrespectful, & outrageous things” about how she co-parents with Robinson.

Jeni claimed that the “Love and War” singer “has made NO effort” to meet her and has caused Robinson “to miss visitation weekends and birthdays.”

“I’m fine with people sharing their version of the story that they’ve created for themselves on social media + television, but what we will not continue to do is involve the son that I raise in someone else’s shenanigans,” she concluded.

A rep for Braxton did not immediately return our request for comment and neither Braxton nor Robinson has publicly responded to Jeni’s claims.

Jeni’s post comes one day after news surfaced that Braxton was engaged to Robinson, who competed for her love on the new reality show “Queens Court.”

During the final episode of the Peacock show, the attorney popped the question to Braxton.

“I don’t wanna be your friend. I wanna be your husband,” the attorney told the Grammy nominee, per ET. “I’m here forever because I don’t see my life without you. And I love you.

“Tamar. Tamar, will you marry me?”

The former WEtv star accepted his proposal, adding, “I can’t believe I found what I was looking for.”

Braxton was previously married to Herbert, 50, for nearly nine years before they called it quits in 2017.

All episodes of “Queens Court” are streaming now on Peacock.
