Justin Bieber keeps mum on reports of dating Selena Gomez

London (ANI): Justin Bieber has decided to keep mum on reports that he is dating Selena Gomez, insisting his private life is nobody else's business. The longtime friends are said to be romantically involved and gossip about a budding relationship was fuelled when the young stars were photographed together on holiday in St. Lucia last month.

But despite the speculation around the pair, the 'Baby" hitmaker has vowed to remain tight-lipped about the gossip. "I don't think it's really anyone's business what my private life is. Some things you just have to keep to yourself," the Daily Star quoted him as telling ITN News.
