BILLIE Faiers' husband Greg Shepherd has been caught on camera while coming face-to-face with a giant shark.
Greg, 39, was filmed in a massive tank of sea creatures for his and Billie's reality show when he had the terrifying encounter.
The couple were on holiday with their three young children at the time and Billie and the kids can be seen looking on in horror.
In an exclusive sneak peek of Greg's brush with danger, he can be seen unwittingly posing with King Neptune's trident underwater.
Standing on the other side of the aquarium window with the children, 34-year-old Billie suddenly gasps: "Oh gosh, is that a shark?!"

The couple's eldest child, nine-year-old Nelly, then uses her hands to signal that there is a shark swimming above him. But Greg doesn't appear to notice.
Greg is also almost brushed by a massive stingray at Dubai’s Aquaventure Waterpark, too.
As tense music plays, Greg admits to the camera: "I'm not going to lie, it is a bit nerve-wracking in the tank.
"Especially when you see a stingray swim past you."
Billie and Greg's son Arthur, seven, also gasps at the stingray as he faces his dad behind the glass tank.
The mood then changes, however, after Billie spots the footwear that her husband is sporting.
Greg is walking around underwater in bright yellow Crocs.
Gesturing to his shoes, she jokes: "Nice Crocs!"
She later admits: "Seeing you in a wetsuit and Crocs... you gave me the ick."
Greg replies: "In 12 years I've never given you the ick and now I've given you the ick because I wore yellow Crocs."

As Greg calls her "shallow", Billie insists it was his entire getup that gave her the 'ick', not just his rubber shoes.
The scenes will air in this week's episode of Billie and Greg: The Family Diaries.
It is the final instalment in the series and fans will also see the couple discussing whether they want to move to Dubai full time.
Billie found fame alongside her sister Sam Faiers on The Only Way Is Essex.
The sisters later starred in their own spin-off series, Sam and Billie: The Mummy Diaries, before Billie decided to go it alone.
The Family Diaries launched in 2021 and Billie and Greg have just wrapped their sixth series of the ITVBe reality show.
Billie and Greg tied the knot in 2019. They welcomed their third child, daughter Margot, in December 2022.
