Natavia Lowery was found guilty yesterday of murdering a ''Realtor to the Stars,'' whose clients included Elton.
Linda Stein's daughter Mandy, who found her mother's body, began sobbing when the verdict was read.
The Manhattan Supreme Court jury took just four hours to reach a decision after three weeks of testimony against Lowery, Stein's personal assistant. Lowery was charged with bludgeoning her boss in her Fifth Avenue penthouse.
Lowery also was found guilty of 20 theft and identity theft charges.
Prosecutors had said the young woman was linked to the brutal slaying by motive -- some $30,000 in embezzlements -- by opportunity as the only person to see Stein that day, and by her admissions to cops, to whom she admitted bludgeoning her boss though not intending to murder her.
Lowery faces a sentence of 25 years to life.
Sentencing is March 22.
