Like Katie, he had been one of the most memorable contestants on the BBC business show, famous for his enthusiasm and one liners such as: "Everything I touch turns to sold."
Writing in her column for The Sun today, Katie said: "I met tragic Stuart Baggs a few times. I think the distance between Stuart the brand and Stuart the man was vast.
"Without a family or kids who need you, the media can be a tough industry to wok in. It may seem glamorous or exciting but kids couldn't care less about that. Mine ring to ask what's for dinner, where their favourite toy is or whether they can go to swimming club with their friends.
"Sometimes you need the mundane in life to remind you that what matters most is not being seen as successful, but helping the people you love the most to be OK."
Stuart was the youngest ever candidate to appear on The Apprentice at just 21 years old. At the time of his death, he was managing director a telecomunnications company on the Isle of Man.
His body was found at a property on the Isle of Man on Thursday morning (30 July). A cause of death has not been revealed but police have said they do not believe it was suspicious.
Among those who paid tribute to Stuart yesterday was Lord Alan Sugar, who said: "Terrible news Stuart Baggs has died. My sincere condolences to his family and friends. RIP. One of the stand out characters of The Apprentice."
