Lori Loughlin and Mossimo Giannulli had US$1 million ($1.4m) of jewellery stolen during a recent burglary.
The 57-year-old actress and Mossimo, 58, had their Los Angeles home broken into on January 3, when masked thieves entered through their bedroom window and raided the actress' jewellery box, TMZ reports.
Neither Loughlin nor her husband - who both went to prison in the college admissions scandal - were at home while the burglary took place.
However, the thieves were spotted by a housekeeper before they escaped the scene of the crime.
