Back in June, Jonnie announced that his wife Jessica had given birth to their second and third children.
The couple, who tied the knot in 2016, became parents to identical twins Rafa and Cormac on June 24.
Yesterday, Jonnie told fans he had travelled all day to spend “precious” time with his young family following a break in filming.
He wrote online: “25 hours of travelling to get back to the family for a couple of precious days.
“To be honest the work days are far from a walk in the park at the moment but it relieves a bit of the guilt I feel from leaving their mum on her own to hold the fort.
“Plus times with this fella [his son Rex] are rarely anything but good ones. #spinningplates #3under2 #twins #identicaltwins #boys #twinsofinstagram.”
