The internet was shaken when two international Hollywood celebrities' unexpectedly popped out of BLACKPINK's Rosé's Instagram Live.

 

A few days ago, Rosé, 23, held an Instagram Live Q&A for her fans worldwide. While Rosé was answering the fans' questions and translating it to English afterward, the viewers were stunned when they noticed the singer and One Direction member Niall Horan posted a "hi" emoticon in the comments section. 

 

Rosé initially did not notice the pop star's comment until the fans called out her attention. For a few moments, Niall Horan joined the K-Pop star's Instagram Live broadcast. 

 

As Entertainment Times wrote, referencing to Pinkvilla's report, Horan was full of joy and excitement while speaking to Rosé and the K-Pop star was able to reciprocate the feeling. The smiles from the two artists also show how much they enjoyed each other's company.

 

The 26-year-old English pop star is a proclaimed Blink, as he previously followed BLACKPINK's personal Instagram accounts. Shortly, in an interview with Capital FM, Horan admitted that the K-Pop quartet is his "guilty pleasure." "I absolutely love them, they're incredible," Horan said.

 

With Horan appearing in Rosé's Instagram Live, the fans started to theorize of the two artists' collaboration, considering both are working on a new album.

 

Niall Horan is not the only celebrity who stopped by Rosé's Instagram Live. American actor Keegan Allen, who played as Toby Cavanaugh in the hit-series Pretty Little Liars, commented, "Congee," making the fans go crazy.
