B. Smith, known as a powerhouse in the entertainment industry, passed away Saturday.

Her husband, Dan Gasby, announced the sad news, adding that she'd struggled with Alzheimer's since 2013. 

According to CNN, Gasby said, "Thank you to all the friends and fans who supported B. and our family during her journey."

"Thank you to everyone for respecting our privacy during this agonizing time."

"Heaven is shining even brighter now that it is graced with B.'s dazzling and unforgettable smile."
