UPDATE: Well, looks like it's official. Producers of The Real confirmed on Sunday that Tamar Braxton is leaving the show. “THE REAL and Tamar Braxton have mutually decided that Tamar will not be continuing with the show for its upcoming third season,” the statement reads. “She will be leaving in order to concentrate on her solo career. Everyone associated with THE REAL appreciates Tamar’s efforts and the contributions she has made to the show’s success, and we wish her all the best for the future.”
Let the speculation begin as to who will replace her. We hear that Raven-Symoné may be looking for a new gig...

First a reported shakeup at The View, then the bitter end of LIVE! With Kelly and Michael and now, The Real. It seems like all the real drama is going down behind-the-scenes of our favorite daytime talk shows. 
The latest "hot topic" is a rumor that Tamar Braxton is on her way out of the hit chat series The Real. According to Love B. Scott, "she wasn’t reading too well with the audience and sales people didn’t find her to be a good fit with advertisers. She was also too difficult dealing with production.”
Shortly after the rumor started circulating, Tamar herself added fuel to the fire with a cryptic Instagram post, which pointed fans in the direction of a specific person who might be responsible for her — allegedly — getting the ax.

In the epic post, she writes, “I love u all but I have been stabbed in the back by someone I stupidly trusted ( not my man or my sisters) I am not about to be tried and tested to snitch ... and it’s not in good taste to tell you who…… but as #tamartians you are very smart and can figure things out on your own. But know that every one who smiles in your face is NOT your friend and is NOT cheering for you and will LIE and try and tear u down to TRY and dim your light."

Fans immediately turned their attention to April Daniels, the wife of Tamar's BFF LaShawn Daniels, as the "who" in Tamar's story. It's not clear how April could have influenced Tamar's position on the talk show, but it's no secret that the former pals have been beefing lately. Tamar even called out the Daniels' on a recent episode of her reality show Tamar & Vince for being fair weather friends who used her and her husband Vince Herbert, and didn't even pay her a visit in the hospital last year during her health scare.
LaShawn was so shook by having his and his wife's names dragged into this mess, that he even took a moment during Diddy's Bad Boy Reunion show to address the rumors in a video:

Okay, then!
To add fuel to the fire, it also appears that Braxton has un-followed everyone tied to The Real, incuding Adrienne Bailon, Jeannie Mai, Loni Love, and The Real itself — with the exception of Tamera Mowry-Housley.
While Tamar herself hasn't directly addressed the mess, she did post this telling message on Twitter:

So, is this really happening or is Tamar playing us to get everyone to tune in Monday morning to find out what's what? Either way, we won't believe anything for sure until we hear it from Tamar's mouth.
