Justin Bieber has responded to reports that claim his relationship with Selena Gomez is over.

Speculation has emerged in recent days that the pop couple's romance has ended, with rumours linking Bieber with model Barbara Palvin.

Speaking on Open House Party, the Canadian star was quizzed on the rumours of a split, with the singer appearing somewhat unsure as to how to reply. He said:

"I don't know what to say."

Bieber continued: "I don't know what's going on in my life. To even assess that it doesn't make sense 'cause I have not made any comment."

Palvin, meanwhile, dismissed links between herself and Bieber, who had his photo taken with the model. She tweeted: "Last time im saying it. please calm down.there is nothing going on w him.i met him and did a pic w him. wouldnt u do the same?:) #friendship."
