Niall Horan and Ali McGinley
One Direction’s Niall Horan is said to be disgusted with his fans over a vicious online rumor which claimed his ex-girlfriend had died after a battle with cancer.

While Harry Styles, Zayn Malik, and Louis Tomlinson have all been targeted by cyber bullies, the rumor about the Westmeath teenager Holly Scally is probably one of the worst to emerge.

“Niall won't be happy to hear how far some of these fans have gone with someone who knew him before all of this,” an insider said.

“This is just some sick hoax—Holly is absolutely fine. She went out with Niall for a while years ago but now has girls giving her abuse online every day of the week,” they added.

Meanwhile, photos have emerged of Horan with a mystery brunette. The Mullingar native was at home in Ireland over the weekend where he was spotted partying with a lady called Ali McGinley.

In one of the photos, the blonde pop star kisses the pretty brunette on the cheek while she smiles ear to ear.

Horan is expected to join his bandmates in London this week before the hitmakers return to the U.S.
