Footy player's model girlfriend blamed for very public family feud.

Sydney Swans captain Kieren Jack’s family feud has been exposed online, after his mother took to Twitter to vent her frustration at being banned from one the most important games in his career.

Donna Jack revealed her son had banned her and her husband, rugby league legend Garry Jack, from attending his milestone 200th game after a family disagreement.

"So sad...you 200 AFL & you don't want us there, your parents. No appreciation for all the yrs (sic) helping you get there," she tweeted at her son on Sunday night.

The feud was reportedly triggered by Jack's parent's disapproval of his model girlfriend, Channel Nine producer Charlotte Goodlet.

Donna's Twitter account has since been set to private, with Jack's father, Garry, only commenting that he "supported his wife's comments". "We are a family," he tweeted. Donna's latest comments come months after she told her son to "practise what you preach". "Family is what gets you there, done ever forget that (sic)," she wrote.
