Singer and former X Factor judge Tulisa Contostavlos has allegedly been caught in a drug sting reportedly involving £800 worth of cocaine.

The 24-year-old is said to have been exposed in an undercover operation, after it was claimed she offered to supply the Class A drug to friends of friends, comparing the cocaine to ‘sweets’.

An undercover reporter for the Sun on Sunday asked the former reality TV show judge if able to supply drugs, to which she responded; “Half my phone book sells it. Of course I can get it for you.

“Half the guys I know are drug dealers. One’s a massive cocaine dealer. He’s my best friend. He’s a gangster – he’s my gangster.”

The ‘Young’ singer then offered to supply the reporter with cannabis, revealing that she uses ‘sweets’ as code for her order. She proceeded to show the reporter texts that detailed her previous orders. Green sweets meant marijuana, and white sweets meant cocaine.

Tulisa proceeded to pass on details of her alleged dealer, who the newspaper then contacted to make a false order.

British police have been quoted as saying ‘We have received information concerning the alleged supply of illegal drugs at a central London location. We are considering the information.’
