The Fresh Prince of Bel-Air star has broken down in tears three times within a week as the pressure of life under 24-hour watch in a rainforest takes its toll.
He wept within hours of entering the camp when he was forced to confront deadly scorpions and leap from a helicopter, and two further emotional moments have left some viewers fearing for his state of mind.
Ribeiro, who became a father just weeks before entering the British survival show, was seen earlier this week (ends29Nov13) weeping and telling his fellow contestants, "I don't know how much more I can take. I don't want to quit but..."
Now it has emerged his wife Angela travelled to Australia on Sunday (24Nov13) with their one-month-old son Alfonso, Jr. - known as 'Aj' - so she is ready to welcome her husband the moment his stint in the jungle ends.
In a post on Twitter.com before setting out on the trip, she wrote, "Packing then heading to the airport. Very ready to see my hubby - hopefully sometime this wk (week). Hoping my lil' Aj does well on his 1st flight."
After arriving Down Under she added, "Aj & I are happy to be on the same continent as (Ribeiro) as we are hoping to see him soon!"
Ribeiro is among a group of stars - including Olympic gold medallist Rebecca Adlington, former Westlife singer Kian Egan, and six-times world snooker champion Steve Davis - who are spending three weeks camped in an Australian rainforest. They have to take part in daily stomach-churning endurance tests to earn food for their campmates.
