JB thinks Lady Gaga is an incredible artist

Justin Bieber has described Lady GaGa as an "incredible artist".

Last week the 16-year-old broke GaGa's previous YouTube record of the most viewed music video, as his Baby video has now been watched by fans more than 250 million times.

Writing on his Twitter page, Justin told his followers:

"It doesn't matter who has more views, what matters is that we have incredible fans that support us".
