Tulisa Contostavlos in laughing gas photo scandal
Embattled British pop star Tulisa Contostavlos is embroiled in a new scandal after she shared with fans a photo of what appears to be nitrous oxide canisters at her house party.
The N-Dubz singer hosted a bash for pals at her home on Sunday (01Sep13) and uploaded photos of the fun on her Instagram.com page.
One image showed Contostavlos and her friends sitting on a couch with what appears to be 'laughing gas' cylinders on a coffee table - but she quickly took down the snap and replaced it with a cropped version.
The substance is legal in the U.K. but anti-drugs campaigners have criticised stars who have been photographed apparently inhaling the gas from balloons.
Contostavlos is no stranger to controversy - she was arrested in June (13) after she was allegedly caught on camera setting up a cocaine deal worth $1,200 (£800) for an undercover reporter from The Sun newspaper.
Contostavlos remains on police bail alongside her rapper pal Mike GLC, who stands accused of selling the illegal substance.
