B. Smith's widower Dan Gasby is a single man again after his girlfriend, Alexandra Lerner, dumped him.

In a recent interview, a broken Gasby revealed his girlfriend left him after Smith died from complications of Alzheimer's.

"She took off and, uh, whatever."

He claimed Lerner (pictured left with B. Smith) never lived with him and Smith. "She was there on weekends - twice a month."

Fans of the late lifestyle guru were shocked and saddened after Gasby, 65, allegedly moved his girlfriend into their Long Island mansion while Smith battled Alzheimer's.

Smith was diagnosed with Alzheimer's in 2013. She announced her diagnosis in 2016 to help raise awareness of the debilitating disease.

B. Smith passed away in February at age 70.
