Lauryn Goodman cried on Thursday's (12 September) episode of Celebs Go Dating as she described "going to war" for her children following her family court battle with Kyle Walker.
The England footballer, 34, shares four children with his wife Annie Kilner.
He fathered a daughter with the glamour model, 33, four years after they had a son together.
Goodman and Walker have battled it out over child support payments, with their legal row hitting the headlines over the summer.
"I think people forget my only priority [is] my children," Goodman said.
"I feel like I'm constantly going to war for my kids and I'm so sick of the battle."
