Speaking out after it was revealed that the estate of the late reality TV star is facing bankruptcy after a million pound tax bill, Jeff said he will do all he can to continue to pay for the private education that Jade so desperately wanted for Bobby, nine and Freddie, eight.
Jeff, 33, told the The Sun he had been 'totally stunned' by the news of the tax demand, and said he 'didn't have a clue' about it as he has no dealings with the trust which looks after the boys' money.
He said that Jade had started putting funds away for her children as soon as she was diagnosed with cervical cancer in 2008.
"The first thing she did was work out how much it would cost to put the boys through private education until they were 16," he said. "The answer was £260,000."
He said he does not 'hate the taxman' as he knows he is just doing his job, but says he hopes that the Inland Revenue comes to 'another view'.
"In her last months that was what drove her on, even when she was so weak and in terrible pain. It was all that mattered to her. She so desperately wanted them to have the upbringing she had never had," the devoted dad revealed.
"I think it was a great comfort to her to know that at the end she had managed to raise the money to give them it. To learn that it might be gone is just unthinkable."
Jeff says he will 'do his best' to pay for the children's education should the trust lose its money.
"She made sacrifices for them to go to their school and so will I," he said. "They have had five years of excellent education thanks to Jade. But if it comes to it and they have to go to good state schools, then so be it."
