The mum of five had a whirlwind six-month relationship with the Argentinian hunk in 2012, even getting his name tattooed on her ankle.
Following their split, she went on to marry former stripper Kieran and have two children with him, son Jett and daughter Bunny.
Katie has gone through a difficult few months, claiming this summer that Kieran had slept with their nanny Nikki Brown – something Nikki has denied – and announcing their separation after four years of marriage.
She also said on Loose Women that her mum Amy is suffering with a terminal lung condition which could mean she only has three years left to live.
A source told Closer that the 39 year old has been speaking to her ex-fiancé after he made contact with her.
“She’s been in touch with Leandro,” they said. “He got in contact when he heard about her mum, and they’ve been speaking regularly.

“They met up in Miami earlier this year and she told him what was going on in her marriage too. She’s fond of him.”
However, a source recently revealed exclusively to OK! Online that Katie and Kieran were “happier than ever”.
Katie arrived to the 2017 Shocktober Fest held at Tulleys Farm Crawley with son Junior, daughter Princess and her soon-to-be ex husband.
They said: “Katie was happy to pose for pictures with Princess and Junior.
“She looked happier than ever. However, Kieran was stood at the side smiling and trying to keep undercover. They looked happy.”
The appearance cames after Katie apparently decided she “can’t live without” Kieran, and so is refusing to kick him out of the family home.
OK! Online has contacted Katie’s rep for comment.
