"[Taylor] wants her friend to be happy and she thinks Niall's a great choice," the report alleged. "Taylor has nothing but respect for Niall and thinks he's totally boyfriend material."

The reports about Selena Gomez dating Niall Horan are fairly new. But it seems the two lovebirds are getting closer by the day.

Hollywood Life reportedly talked to a source who claimed that even before they started dating, Niall Horan has been very open about his feelings for Selena Gomez.

"He confessed to her that he had been waiting for her for a long time. He has no problem being vulnerable with her whatsoever and his very vocal about how he absolutely adores her," the insider said.

In fact, Niall Horan is allegedly ready to take their dating relationship to another level as the One Direction hottie invited Selena Gomez to come with him to his hometown in Ireland.

"Niall really wants to introduce Selena to his family and show her where he grew up. He also wants to take her to the countryside and show her his favorite spots," the article added.

For her part, Selena Gomez is reportedly just as excited about what the future holds for her in dating Niall Horan.

"Selena is very excited to have a no-nonsense real relationship and that is what Niall offers," it said. "When she goes out with Niall or is seen doing things pro One Direction she doesn't want it to look like she is dissing Justin."
