Selena Gomez and Niall Horan sparked dating rumours when they were spotted by a concert-goer in Katy Perry's "Prismatic" concert held in London's O2 Arena. According to Cambio, rumours that Selena and Niall were on a date surfaced after a grainy photo of the pair in the concert circulated on Twitter. However, a source confirms to British tabloid The Sun that Selena and Niall Horan are not dating, whileTaylor Swift thinks Niall is good for the "Come and Get It" singer.

"Niall and Selena have always got on well and communicate regularly. It will always be tough having a serious relationship given their schedules, so they're just having fun."

However, Selena's best friendTaylor Swift thinks that Niall is a gentleman and is good for Selena.

Selena Gomez has been leaning on her friend Taylor ever since her split from pop star Justin Bieber. According to Hollywood Life, Taylor Swift found the perfect remedy for Selena in a "complete gentleman" named Niall Horan. It's no secret that Swift has never been a fan of the Selena-Justin relationship. Now Hollywood Life reports that Swift wants Niall for Selena.

A source told Hollywood Life that Taylor adores Niall Horan and thinks he is a gentleman. He would be perfect for Selena. The source added that the only way Selena can ever forget about Justin is to hang out with the "good ones" and she definitely has Niall in mind.

"Taylor had to persuade her to go out with Niall and promised her she would have a great time. She has been telling Selena, 'just trust me' and Selena has been doing just that," the source says.

Was Selena taking Taylor Swift's advice thus the "date" in the Katy Perry concert? Eyewitnesses saw Selena and Niall hanging out at the concert and it would be their second "date" since their hook-up in London in February.

Selena Gomez has 20.4 million Twitter followers and Niall Horan 18.6 million. Let's read what they have to say about their "date" rumour.

@CaliTracking1D Um, I don't think he'd date her since she's Justin's ex, and I don't think he'd want to create tension there.
