After she was sensationally cleared of murdering British student Meredith Kercher, the 24-year-old appears to have dumped her long time Italian beau in favor of a home grown model.
Classical music student James Terrano is studying classical music, specialising in guitar, at Seattle’s University of Washington where Knox was studying languages - which is why she ended up in Italy in the first place.
It's believed she is about to resume her studies.
The pair are believed to be sharing an apartment in Seattle's run down Chinatown neighborhood, although they were tight lipped when approached by The Mail On Sunday.
But his nuclear physicist brother William, 27, confirmed the pair were an item.
He said: "Yes, she’s dating my brother. They have known each other for years. We’ve all been friends since before Amanda went to Italy."
The news emerged as Sollecito confirmed that their doomed relationship is over as he finally broke his silence with an in-depth interview on Italian TV.
