Niall Horan and the rest of One Direction haven't collaborated with Justin Bieber yet, but Niall and the Biebs did recently bond with one another over playing video games.
Not too long ago there was a rumor that Justin and Niall almost got in a fight because Niall and Selena Gomez were flirting with one another at the Kids' Choice Awards. However, it should be fairly obvious that there's no bad blood between the Biebs and Niall now since they took the time to hang out together in London (especially since Niall was recovering from food poisoning).
Alfredo Flores probably made a lot of girls say "OMG" when he revealed that he and Justin Bieber were hanging out with Niall Horan. Here's what he wrote on his Instagram account: "Me and Justin playing NBA2K12 and he wanted Niall to instagram the score but he doesn't have instagram.... Yet lol."
Directioners probably wouldn't mind if Alfredo and Justin got Niall hooked on Instagram since it would mean that the One Direction star could share lots of cool photos with them. But why did Justin Bieber want Niall Horan to share the game score with Directioners and Beliebers? Was it because he was beating Alfredo Flores that badly? Nope; it was because the score was tied at 69 to 69 (the Biebs has such a dirty mind).
Berectioners (fans of Justin and One Direction) will be relieved to know that the Biebs and the British boy band get along so well so they won't feel forced to choose sides. 1D and The Wanted might seem like they're replacing Justin in the hearts of teen girls everywhere, but the Biebs isn't worried and is even showing that there's room for everyone by embracing the boy bands.
Hopefully Justin has a little more time to hang out with the rest of 1D in London - he loves pulling pranks just like 1D, so surely he'd love to get in a bit of trouble with Niall, Harry Styles, Louis Tomlinson, Liam Payne, and Zayn Malik. And if he does hang out with the womanizers in the band, hopefully Selena Gomez doesn't worry too much.
