Not even three months after welcoming youngest son Prince Louis into the royal family, Prince William jetted off on official business to the Middle East - leaving wife Kate Middleton home alone with the kids.
The Duchess of Cambridge was left 'worried sick', Star magazine claims, after William was caught in an Instagram story with Israeli supermodel Bar Refaeli.
Meeting the Duke of Cambridge at a private party in Tel Aviv, the supermodel bragged on social media with videos of the two, writing: 'Prince Charming.'
'Bar's comments about Will being so handsome raised several red flags for Kate,' a source spilled to Star.
'Kate wanted to know what went on behind closed doors to make Bar say that.'
The insider adds to the US publication, 'It's hard for Kate. She's juggling three kids while her husband is off meeting supermodels!'
The royal family has not responded to Star's claims.
