Justin Bieber Tight-Lipped On Selena Gomez 'Split'

Justin Bieber has said that he doesn't "know what to say" on [uuid=78045fad-e023-40e8-afb0-50d68062350e]Selena Gomez.

The teen pop idol was questioned about the rumours that his relationship with singer and actress Selena was over on US radio show Open House Party, but simply responded: "I don't know what to say."

And he went on: "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."

But while 19-year-old Biebs was playing his cards close to his chest, the rather attractive Hungarian model he has been linked to was more forthcoming on the subject.

Barbara Palvin took to her Twitter account to insist that there was nothing going on with the pop star.

She wrote: "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."
