The former glamour model accused Dwight of being able to fly to the US but not come to her home in West Sussex to visit their son Harvey, 14,
An angry Katie tweeted: “Why don’t you get a flight to West Sussex and see your son Harvey. He has only been waiting 10 years… you know the four is always open #d**k (sic)”
And just in case anybody didn’t know what she was talking about, Katie, 36, included a link to the story about Dwight’s travel woes.
It’s not the first time Katie has laid into former Manchester United and England player Dwight, who is the father of her eldest son Harvey, born on May 27, 2002.
Katie has previously accused ex-boyfriend Dwight of not seeing their child, who suffers from a range of disabilities including Prader-Willi syndrome and visual impairment.
