Selena Gomez and Niall Horan are really in love with each other. According to HollywoodLife.com, the One Direction singer can make her feel like she's "the only woman in the world" with the way he treats her and his sweet words.

A source told the news outlet, "[Selena's] confidence right now is sky high. Doing the Victoria's Secret Fashion Show, and all the love and compliments she got from all the angels, was a huge boost. And of course, this thing with Niall hasn't hurt. He makes her feel like the only woman in the world."

On another note, Selena reportedly told her ex-boyfriend Justin Bieber that neither she nor Niall tried to betray him. "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," another source explained.

"Had [Selena] been in a committed relationship with [Justin] this never would have happened in the first place," the source continued. "She explained to Justin that it was never her intention to hurt him and that things with Niall just happened naturally."

After learning of the news that Selena and Niall were spotted kissing at Jenna Dewan-Tatum's birthday party, Justin posted on Instagram a throwback picture of him holding hands with his ex-girlfriend. Later on, he posted on the social media a snap of mystery girl. Most recently, it's revealed that the girl is a 17-year-old part-time babysitter, named Cindy Kimberley, who lives in the Costa Blanca resort of Denia near Benidorm, Spain.
