Tamar Braxton has officially withdrawn from the competition on "Dancing With the Stars" due to a serious health issue.

The singer -- who briefly visited the hospital on Nov. 9 after suffering the symptoms of what she believed was pneumonia during rehearsals and then went on to compete -- announced her decision on Instagram in the wee hours of Nov. 11.

"With a Heavy heart I regret to inform you that my season of #dwts has to come to an end along with the rest of my tour dates with @musicbykem,"she captioned a photo of herself holding a green teddy bear while curled up in her hospital bed with partner Val Chmerkovskiy.

"After yesterday's final #dwts performance I went back to the hospital (after the doctors didn't want me to leave in the first place) only to find out that I don't have pneumonia but something way more serious and that is having several P.E.'s (blood clots in both sides of my lungs)," she continued. "As you all know I will be the first to always encourage anyone to push through any obstacle that comes along one's way. But in this case, my health is my current obstacle. .. And in TRUE #tamartian form I must go about this the exact same way as I would anything else. I woke up to a mirror and saw myself this morning and that makes me the winner because that almost wasn't the case. 🏆Take care of yourselves... I love you and thank you ALL for your support❤️ p.s. Big hugs and kisses to my boo @iamvalc for being beyond a friend, brother and the BEST partner EVER😘🙌🏽🙌🏾"

Sadly, Tamar is not the only "Dancing With the Stars" contestant who's faced serious health issues this season.

In October, Kim Zolciak-Biermann discovered that she had a previously undiagnosed heart condition after she suffered a mini-stroke in September during her time on the reality-TV show. She underwent heart surgery late last month.
