While he is very close to his mother, Bieber has another woman in his life, Selena Gomez, and says he refuses to hide her relationship with her.
The couple - who began dating in 2010 - are often photographed holding hands or enjoy quality time together, and the 'Baby' hitmaker believes it would be "healthy" to be otherwise.
