Yesterday, Louise took to her Instagram story to share snaps from her most recent holiday.
The star appears to have joined her ex-husband Jamie Redknapp, 45, and their two sons Charley, 15, and Beau, 10, on holiday in Portugal.
She shared a picture of her with her son Beau followed by a selfie of her ready for a night out.
Louise’s ex Jamie has also been sharing pictures from his holiday with their sons, his dad Harry Redknapp and mum Sandra.
Earlier this week, she shared an off-the-cuff snap of Charley in a restaurant.
She captioned the picture: “Trying to sneak a picture of @charley_redknapp but it’s not happening.”
Louise also said she had been “partying”, during her time away.
“Last of the big partyers,” she captioned the upload. “Home for a cuppa.”
During the holiday, Jamie revealed why their son Charley was “not happy” with his dad Harry.
The football pundit shared a video of the group dining at a restaurant.
Jamie filmed his son Charley looking over at Harry, who was tucking into a dessert.
He captioned the video: “Charley’s not happy, this big man is eating his sticky toffee pudding.”
Louise and Jamie divorced after 19 years of marriage in 2017.
