Danielle Lloyd has reportedly spoken to lawyers over her husband's appearance on Celebrity Big Brother 2017.
DigitalSpy reports that Danielle revealed she had been in talks with her team after Jamie's comments on CBB.
In a now deleted tweet, Danielle told her followers: "when you bring your puppy with you visit [your] lawyer. #slander."
While Jamie has not mentioned Danielle by name on the show, he has spoken about his 'ex wife' a number of times.
In one chat he claimed: "When I was with her, I was earning really good money and she kind of expected that to continue. But I'm not on that money no more.
"I am trying. I am paying out a fortune. It's so f**king draining, the constant battle. When I was at Fulham I was paying out pretty much everything I was earning."
And before entering the house on launch night, Jamie said he was taking part in the show because he had "lost a few quid" after his divorce.
Speaking to The Sun, Jamie said: "I lost quite a bit in my divorce so it's always nice to be offered money. At the end of the day we're here to make a living.
"I lost a few quid. This hopefully gives me an opportunity to build a future for me and my kids."
Revealing he was up for romance in the house, the paper quoted Jamie as saying all he wanted from a future partner was "One that doesn't take all your money."
Celebrity Big Brother continues nightly on Channel 5.
