Reports claiming Niall Horan's girlfriend is Laura Whitmore have again surfaced after the two were spotted partying at the star-studded Red Bull Tropical Edition party. The party was held at London's The Box nightclub.

The "Up All Night" singer shared a snap of him with the Irish presenter and captioned it, "Great craic last night, serious dancing done as per with @thewhitmore"

Other photos from that night even show the "Summer Love" crooner whispering in the blonde beauty's ear.

Three months ago, Niall Horan already sparked romance rumours with Laura Whitmore when he shared a short yet sweet message for her on Instagram:

"Happy birthday @whitmore! What a great party last night,loved it! Love you! Have a nice day!"

The "Girl Almighty" hit maker was pertaining to the birthday bash Laura Whitmore threw for her 30^th year. However, fans did not make a fuss out of the photo because Niall Horan's girlfriend that time was Melissa Whitelaw.

Fans have to note too that Niall Horan's "girlfriend" Laura Whitmore has been his longtimefriend.

In an interview with Heat magazine last year, Laura Whitmore claimed that she considers the pop star her brother.

"I was never seeing Niall. He's a child. The most embarrassing thing about that is that people thought we were together."

"I love Niall, he's lovely. But I'm 28. He's a boy. And he kind of looks like my little brother. So, no," she explained.

Niall Horan and Melissa Whitelaw dated for three months but they parted ways last June because of the band's busy schedule.

"Niall and Melissa did well to keep their romance low-profile during their time together. They were really close and had fun whenever they went out together," an insider told The Sun.

"But realistically they always knew it was going to be tough, keeping a relationship going with such distance between them."
