Ariana Grande Dating News: ‘Break Free’ Singer Spotted with One Direction’s Niall Horan... Again!

Ariana Grande has been spotted hanging out with One Direction's Niall Horan once again!

Although the "Break Free" singer has previously slammed rumors that she is dating Horan, the rumor mill continues to churn. According to the latest stories, Grande and Horan were seen attending a birthday party in Barcelona, Spain last week.

The Daily Mail reported that although the two young stars arrived at the Botafumeiro restaurant separately for Alfredo Flores' 26th birthday celebration, they partied together throughout the night.

Grande, who wore a white crop top, was already in the city. She was scheduled to perform at Palau Sant Jordi Tuesday night (June 16). Horan, who recently performed in Brussels, Belgian, however, had to head out of Barcelona to perform with One Direction in Denmark.

The rumored couple was first seen hanging out in London at the Cirque Le Soir with mutual friends, who included Grande's ex, Nathan Sykes. Grande was later photographed leaving Horan's place early in the morning but sources dispelled rumors that they were dating.

A rep told HollywoodLife.com, "Ariana is friends with Niall. He had a big party that she was leaving."

The pair continued to hang out during Grande's stay in London.

In response to the early rumors, Grande told Britain's The Sun, "A girl can be friends with someone with a d**k and not hop on it... I'm tired of needing to be linked to a guy. I'm not Big Sean's ex. I'm not Niall's new possible girl. I'm Ariana Grande."

Grande dated Big Sean for eight months before they called it quits in April.
