The former "Full House" star has been a mainstay on the Hallmark Channel - starring in numerous shows and movies since coming on board in 2013.
She's among the so-called "Christmas queens" who topline a slate of popular holiday movies.
Hallmark has chose to cut ties with actress Lori Loughlin - the longtime face of its cable channel - following her arrest in the ongoing college bribery scandal.
Market strategist Laura Ries says it's an open question of whether audiences can separate Loughlin from the characters she plays.
Loughlin and Mossimo Giannulli were accused on Tuesday of paying bribes of $500,000 in a scheme that involved cheating on college entrance exams to help their daughter and another daughter, Isabella Giannulli, get into the University of Southern California, according to court documents. Their lawyer has declined comment.
"We are saddened by the recent news surrounding the college admissions allegations. We are no longer working with Lori Loughlin and have stopped development of all productions that air on the Crown Media Family Network channels involving Lori Loughlin including 'Garage Sale Mysteries, ' an independent third party production", the Hallmark parent company said in a statement.
Paris-based Sephora says in a statement Thursday that after reviewing the developments, the company has ended its partnership with 19-year-old Olivia Jade Giannulli "effective immediately".
