The restraining order that Thomas Kinkade's wife applied for against his mistress just days after his death has been granted, Breaking Celebrity News has learned.

Nanette Kinkade argued that because Thomas' mistress, Amy Pinto-Walsh, was also his assistant and had signed a confidentiality agreement in 2011, she had no right to speak out about him after he died and wanted to ban her from "defaming, criticizing, disparaging or discrediting Kinkade, Nanette Kinkade, or any company owned by Kinkade."

A judge found in Nanette's favor and the restraining order was granted.

As Breaking Celebrity News exclusively reported, Thomas adored Amy and the two planned to tie the knot as soon as his divorce from Nanette was finalized.

"Amy was already part of his circle of friends and that really enraged Nanette. She was furious and humiliated that he not only cheated on her, but moved on so quickly and publicly with her," the insider told us.
