Of course, fans and friends of the One Direction cutie have taken to Twitter to greet Niall a very happy birthday. Take a look at Niall Horan's transition from "X-Factor" to sensational boy band member.

Niall Horan like everybody in the music business started out in humble beginnings on a reality show. Horan along with Harry Styles, Liam Payne, Louis Tomlinson and Zayn Malik were a few lucky contestants who had made it to "X-Factor." Despite losing on the show, the boys along with Uncle Simon, their innate good looks and incredible talent supercharged them into stardom.

In a matter of months, the boys have gone from zero to hero. At the last MTV Video Music Awards, the boys scooped a whopping three awards of which include best music video for their hit song "What Makes You Beautiful."  Even with three awards in tow, the boys have their sights set on a higher note with a new album set for release.

Of course, along the way to musical careers, the boys grow along with their fans. One member who has aged a year and is currently celebrating it with Canadian crooner, Justin Bieber, is Niall Horan. The pair had enjoyed a night of noodles. Though it appeared as if the boy bonding wasn't enough, Justin and Niall both flew to England to celebrate Horan's birthday.

"@justinbieber @AlfredoFlores @JoshDevineDrums chillin with the kings neighbors!" tweeted Niall.

"Lovely voicenote from @justinbieber @DannyRiach @zaynmalik @AlfredoFlores wishing me happy birthday, love those dudes!" said another tweet by Niall Horan.

Friends of the Irish boy weren't the only ones to greet. Horan's hoards of fan girls and guys all took to Twitter despite the different time zones to greet the birthday boy. Some fans however are waiting for a special tweet from someone else. If fans would recall, Niall Horan had tweeted Demi Lovato a birthday greeting containing the word "honey." Now, it's time for Demi Lovato to return the favor with a special birthday greeting of her own.
