Not all female fans hanging on to Niall's every word

There's at least one female out there who has no problem hanging up the phone on pop sensation, Niall Horan - his granny!

Niall was bemused when, on Monday, she told him she had to go, as she was awaiting an item on One Direction on radio.

The Mullingar lad tweeted from his @niallofficial account to tell his fans what happened:

Was talking to my nanny earlier and she said,have to go !Listening to the radio they're gona talk about one direction after the break! Haha

Niall was on radio himself this morning, interviewed by guest presenter Nicky Byrne on The Tubridy Show on RTE 2fm.

One of the highlights of Niall's year to date was taking part in a training session with Real Madrid last week, he revealed.
