Bobby Horan, father of the Mullingar native and One Direction heartthrob Niall Horan, is nothing but proud of his son and his bandmates’ recent unprecedented success in the US. Bobby does, however, worry of the “bubble bursting” on the lads’ quick rise to fame.

Speaking with the Irish Sun, Bobby Horan said "The only thing I am worried about is hopefully there will be a long period at the top. The comedown from that I am a little bit worried about. It's always in the back of your mind — you are up there on a high and it's a big drop after that."

Just last week, One Direction made music history by becoming the first ever UK group to debut at number one on the US music charts. They beat out the likes of The Beatles and The Spice Girls by claiming the prized recognition.

Bobby Horan went on to say that his son Niall is handling the newfound fame rather well. "Niall seems to be coping very well with everything, better than I would be anyway!,” said Bobby to radio host Ryan Tubridy. "He is absolutely buzzing. He is on a real high now.”

Bobby went on to note how Niall is mindful of keeping his friends close to him, despite rising so quickly to international fame. "He keeps his friends close to him and he rings them and he brings them over to England when he's there. That's very important to me. I'm delighted he is keeping his friends close to him."

Though proud of his son, Bobby Horan not surprisingly misses having Niall around at home in Mullingar. "He came home at Christmas for six days and on and off you might get him. He's happy with what he's doing and we are happy that he's happy."

Speaking with American radio host Ryan Seacrest, Niall Horan noted one moment when he was overwhelmed by fans’ reactions. "The craziest thing that's happened was when we arrived in France. There was loads of thousands of people waiting for us at the train station, and we weren't expecting it. It was mad!"

Along with landing at the top spot on the US music charts last week, One Direction became hotly embroiled with rumors that Nickelodeon had the signed the group on for a new television show.

However, Niall’s bandmate Liam Payne insisted there is no deal: "Funnily enough I think there must have been some misunderstanding. We are doing the Nickelodeon Kids' Choice Awards, but as far as a TV show goes we haven't sat down and had that conversation.”

Much to the relief of many ‘Directioners,’ the intense fan base of One Direction, who had quickly taken to Twitter in the wake of the announcement to express their dissatisfaction with the boys heading to Nickelodeon.

Niall added that "It's nothing that I know about. There's no sign of a TV show in the pipeline. Nickelodeon have been amazing to us. They have helped us out so much while we've been here, and we're performing on the Kids' Choice Awards with Katy Perry."
