Sorry girls but it appears that Niall Horan is off the market once more. The One Direction Irish member is said to have gotten back with ex-girlfriend, Zoe Whelan. Rumours claim that Niall Horan has actually been dating Zoe for months but the couple has kept the relationship tightly under wraps.

Afraid that the public eye might wreck his relationship, Niall Horan of One Direction has kept his relationship with Zoe Whelan a secret. Reports claimed that Niall and Zoe have gotten back together months after they broke up this year. However, sources close to Niall claim they didn't really break up.

"Niall wants everything kept completely under the radar as he feels they simply won't survive if they're being watched," reports Hollywood Life, adding, "But the truth is, he's mad about her and when he's in Ireland they're spending almost every second together."

"Directioners" might not have noticed Zoe Whelan during shows because the insider adds that she's a regular at the boys' concerts and tours.

"She's flown out on four different occasions to meet him over in London and be close to him. Although they would prefer to keep the relationship quiet, they actually get to hook up together a lot more than you'd think and Zoe is a regular face backstage at their gigs," adds the source.

While Niall might not have the approval from all his "Directioners," Harry Styles, Zayn Malik, Louis Tomlinson and Liam Payne have got Horan's back when it comes to his lady love.

"All the other lads in the band are aware of how much he likes her and even though things have been on and off at times, he's always felt she was the only girl he wanted a proper relationship with," explains the source.
