He is one of the most famous singers on the planet but Justin Bieber obviously needs his downtime from being recognised - although he may need to start rethinking his disguises.

Canadian teen crooner Bieber was spotted out and about in London doing some shopping with pals as he continues his UK tour.

The leather-clad Baby singer, who now has more Twitter followers than the population of Canada, made the most of his time off with pals as he hit up ACNE on Dover St in the UK capital.

Bieber took off his clever disguise inside the shop but outside he kept his pretty face covered with the black gas mask.

Justin, who just returned from playing in Manchester, may have popped on the disguise but he slapped on his trademark hat as he left the shop.

It was reported the Boyfriend hit-maker ordered £500 worth of room service when he stayed in Manchester.

Insiders revealed Bieber's crew ordered burgers, steaks, chips and desserts at five-star Radisson Blu Edwardian Hotel - all washed down with vodka, setting them back about £500.

Bieber reportedly impressed 17-year-old aspiring singer Ella-Paige Roberts-Clarke by taking her on a date in a Rolls Royce... just a night after taking her to Justin Timberlake's BRIT Awards after-show concert.

According to the Sunday Mirror, the 18-year-old Canadian star reportedly sent a Rolls Royce round to her home to pick her up and escort her to the flashy five-star Lanesborough Hotel in London where he was staying as he readied kicking off his UK tour.

Just hours after his wild tour of London clubs, including kindly giving two young women a lift home on Tuesday, Bieber was spotted taking Ella to Timberlake's BRIT Awards after-show concert.

The following day the MailOnline revealed her identity as the 17-year-old ambitious singer from Norfolk who friends said was 'determined to become famous'.

A source told MailOnline: 'Since she was at school she always wanted to be famous. The weird thing is she has worked so hard but just being seen with Justin Bieber is probably going to make her career.'
