"He’s in a new relationship and he’s happy and she’s lovely – I get along with her."
When she was pregnant with Lenny in 2008, she revealed she had been with Bill for two years but kept his identity private.
The couple ended up splitting up but Jo said they remained pals and co-parented their son.
The singer told People at the time: "Even though I'm classed as a single mum, I've got my family and friends and the father is going to be involved.
"I think we've made the right decision. If you stay in something that won't be happy, that's not good for the baby. He's going to be loved by both his parents, and he's not going to see us feuding or arguing."
