Selena Gomez and One Direction's Niall Horan have been sparking some pretty serious dating rumors even since they were spotted kissing at a party earlier this month. This left fans who were rooting for her and Justin Bieber to get back together, for what seems like the hundredth time, devastated, especially since he had just serenaded her with a love song a few days prior, but it turns out this has more to do with Bieber's commitment issues than it does Gomez.

"[Selena] explained to Justin that it was never her intention to hurt him and that things with Niall just happened naturally," an insider told Hollywood Life. "She begged him not to be angry at Niall and not to think that he tried to deliberately try and betray him. Selena told him that Niall never tried to go behind his back, and that had she been in a committed relationship with [Justin] this never would have happened in the first place."

The source continued to explain that things would have been different if Bieber would have made it clearer that he possibly wanted a commitment with her upon reuniting. They also reportedly said that Horan is ready to commit, unlike Bieber, which is something Gomez has been waiting to hear for a long time.

Horan's band mate Harry Styles is also all about this new relationship and thinks that they're really great together.

"Harry is totally happy for Niall and Selena," another source told Hollywood Life. "He thinks she's a super sweet person and he's glad that their friendship blossomed into something romantic. He thinks they're a great match and is pleased that Niall has found someone that makes him so happy."

When they were first seen kissing at the party, which was Channing Tatum's wife Jenna Dewan Tatum's 35th birthday party in L.A., an eyewitness said that they spend the entire evening by each other's side.

"Niall and Selena definitely seemed very close and like they were together," the source told Us Weekly. "Niall got there first with his body guard, then the next thing I know, I looked over and Selena was there. They were very close together, talking and whispering...Niall and Selena were kidding in the middle of the club, in front of everyone...[They] left together. She grabbed his arm on the way out and held onto it."
