Kerry Katona’s ex-husband Brian McFadden used Twitter to call her a "pig-faced mole" and say that she is “dead” to him, it’s been reported.
Tensions between the pair rose after Katona told a tabloid that the former Westlife star, who’s now based in Sydney with Delta Goodrem, hardly ever keeps in contact with his children.
She also alleged that the pair’s youngest daughter Lilly "doesn't really know who he is".
McFadden then wrote several angry responses on Twitter, according to Digital Spy, which were subsequently removed.
One apparently said: “Wish certain f**ks would stop selling there [sic] stories to rags and get a real job. Kerry Katona you are dead to me!”
With those posts now removed, he seemingly added on his page: “sorry for bringing my personal anger to twitter.... lets have some fun”.
A source told The Sun: "He took the comments down because he doesn't want to stoop to Kerry's level. It's unlikely they'll ever speak again."
Meanwhile famed gossip blogger Perez Hilton had responded on the social networking tool to tell a clearly irate McFadden: “Go protect your babies! Go get 'em!”
The star responded via the site: “I've tried twice perez... and twice the british courts went against me... go figure!”
