Donal MacIntyre's marriage is said to be in trouble, after his wife reportedly posted a livid message on Facebook.
Ameera MacIntyre, who has three children with her husband of nine years, reportedly shared a family picture, with the caption:
"How could you ruin this beautiful family?'
According to The Sun, her friends rushed to comfort the mum, with one writing:
'How could someone do this? Is there no hope?'.
A spokesman for the Irish journalist said: 'We won't be making any further comment. It is of course a difficult time for the family and everyone close is giving the best support to both Donal and Ameera.'
Over the years Donal has worked as an undercover journalist on a range of dangerous documentaries, exposing criminal gangs and sex traffickers.
The 49-year-old previously admitted his career path has affected his personal life, having relocated over 50 times due to threats from those he has exposed.
Donal and Ameera are parents to Allegra, 12, Tiger-Willow, 8, and 3-year-old Hunter.
