The 41-year-old reality star and former publicist is widely expected to be among the housemates revealed on tonight's Channel 5 launch show.
We can't wait!
Jonathan was snapped in London on Monday evening (4 January) heading to Japanese restaurant Roka with his glam girlfriend Anat Popovsky.
He's known as a dedicated foodie, owning restaurants in the US and frequently posting about his meals to Instragram. He's also founder of entertainment and lifestyle website TheDishh.com. We wonder how he'll cope with CBB rations!
Jonathan flew into the UK just after New Year and made his first British television appearance yesterday, joining ITV's Lorraine for a sit-down interview.
Of course, he was quizzed about his famous bestie Kim and her family, but also about those rumours that he'll be going into CBB. Playing coy, he pretended not to know what Lorraine was talking about. Naughty!
