Baggs was fired by Sugar in last year's semi-final after surviving several trips to the boardroom.
Asked if he was still in touch with Baggs, Sugar told Heat: "Not really. I think he's too busy mapping out his new career in... I don't know... media? I had a couple of short conversations with him to give him a bit of advice.
"Let's hope he takes heed of it one day, but he's been seduced by some second-rate TV channel to do something now, so we'll all sit back with bated breath to see how that turns out. I warned him that he'll just be the target of people who want him to make a fool of himself."
Earlier this year, Baggs was confirmed to appear on Channel 4 show Celebrity Five Go To... alongside Christopher Biggins, former singer Sheila Ferguson, model Paula Hamilton and ex-cricketer Ed Giddins.
Sugar continued: "If he could contain his enthusiasm and energy and direct it into really getting on with doing something, rather than feeding his ego and trying to be funny... If he could use his intelligence on a project, he could be a very, very successful person.
"That's what I told him. But unfortunately he's young. You tell a child not to touch a kettle, but the only way they find out why is by touching it."
Sugar added that he would not give Baggs a job "at the moment", but that he might reconsider "in a few years when he's burnt his stupidity out".
