Niall Horan's brother catches feelings on Twitter but claims he was hacked!

Los Angeles - Niall Horan's brother appears to have blasted him on Twitter.

The One Direction star's elder sibling Greg has fuelled speculation of a family feud after appearing to hit out at the singer for not visiting his nephew Theo, after the 15 month old was hospitalised in Dublin earlier this month after sustaining a nasty burn.

In tweets which have now been deleted, Greg wrote: "I wonder when Niall is calling to see theo I do wonder."

"Sick of being hurt by loved ones really am. (sic)"

Niall is believed to have returned home to Mullingar, Co Westmeath, after completing the group's huge Where We Are US tour but it seems his brother has no idea of the Best Song Ever hitmaker's movements.

He tweeted last week:

Does anyone know if 1D are touring Europe next year 2015

Little Theo has his own website - where fans can buy coins to commemorate his recent first birthday - and even a twitter account.

After suffering the burn on a range fire his tweets read:

I had a little accident and I have to go to crumlin hospital a little sad and my mammy very sad x

After all the commotion caused, Greg claimed on Monday that he was hacked and had nothing to do with the previous tweets.
