Since her rise to mega stardom, R&B singer Tamar Braxton have been busy burning that mid-night oil from working in the studio, doing countless promo-runs for both her album and family reality show to co-hosting her own daily chat fest (The Real) and going on tour.

But like every celebrity, sometimes a break in-between help the body to re-energize itself, something Braxton hasn't been doing lately. On Friday night, the "All The Way Home" singer gave her Las Vegas fans quite the scare after nearly passing out in the middle of her onstage "Love & War" tour performance.

The singer's husband and manager Vince Herbert also had to assist his wife off stage, where she took a long break before her next set performance. She later talked about the incident via Instagram by posting a letter of appreciation to her fans:

"I really felt like last night was #lightsout for me! I felt sooo bad I was shaking. I honestly couldn’t remember a lyric ( which is nothing new) a dance step (every night) but…I never lost my MYSELF where my body took over my mind and left me helpless. I wanted to stay but I couldn’t. I wanted to drink water and catch my breath but I couldn’t," Braxton wrote.

Braxton went on to say that she was "powerless and heartbroken" and didn’t want to give up on her fans so easily:

"I tried to get up and go back 3 times but I couldn’t move, talk, sing & worse, breathe. Not until I heard how after all that time past that you ALL was waiting for me no one left!"

"I GOT my life last night cause u gave it to me! I walked back on stage feeling defeated, frustrated, scared, VOICELESS and STILL u ALL excepted &still loved the REAL Tamar."

"THAT is how my voice came back I had a TON of energy and you even sang every song until I could do it by myself!! I KNOW you love me for ME! I’ll never forget how u changed my life last night & you all have left me feeling that I will NEVER be the same! Thank you for saving me!"

I don’t think the level of exposure changed my relationship with Vince, I think the work that we do together changed our relationship. It went from me supporting Vince and all the things that he was doing to it switching around. He supports me and everything that I’m doing. It’s like our relationship has taken a turn because communicate because we have to. We have to get along or else we couldn’t get anything done. The level of respect for each other has increased and also, we’ve grown up because of it. The maturity of the relationship has matured. I know I’ve matured. Now he’s a father, I’m a mother. We don’t have time for that.

Everything I post is not personal for me, let’s just go there. One of my post I call “Instagram psychics,” everybody thinks they know what the hell you’re talking about. There was a week where there was a lot of side chick posts on Instagram, and I was saying this is a repost—I don’t know how that turned into the blogs saying that Vince is cheating on Tamar. I don’t play with that. [laughing]

I just thought it was interesting that being a side chick is something that people are proud of these days. I wrote about this in my book being a side piece, sometimes you don’t know. But when you do know, you shouldn’t be proud of it. If you’re 100 percent woman, you should be loved 100 percent. One of [the posts] that worked on my last everlasting nerve said, “I can’t help it if he chooses to be with me more than you.” Excuse me!? And that’s what I was saying, this is when you can tell that you’re not somebody’s wife because that should bother you. Why should it not bother you that this man gets up and leaves you to go home? Wait a minute, you have to want more than this. I just wanted women to know that and it somehow became Vince cheating on me, which was sad.

Watching yourself on television it’s like, wait a minute! I didn’t mean it like that! It took me a long time to understand that just because somebody is talking about something around me or to me does not mean that they want me to always talk or have something to say or want my opinion.
