Justin Bieber writes mum song as b'day gift

Washington, Mar 22 (ANI): Justin Bieber has paid a tribute to his mother, Pattie Mallette by writing a song for her as an early birthday present.

After a day out with her famous son, Mallette took to her Twitter account to express her joy.

"Had the BEST mother-son date ever w @justinbieber. Dinner and a movie and gave me and early bday present - he wrote me a song!#MomentsToCherish. (sic)" Contactmusic quoted her as tweeting.

The 18-year-old pop star responded: "love u (sic)"

While he is incredibly close to his mum, Bieber also has another lady in his life, Selena Gomez, and has said that he refuses to hide his relationship with her.

The couple - who first started dating in 2010 - are often photographed holding hands or enjoying quality time together, and the 'Baby' hitmaker believes it would be "unhealthy" to have it any other way. (ANI)
