'X Factor' UK's Tulisa held on drug claim, reports say

British media say singer and former U.K. "X Factor" judge Tulisa Contostavlos has been arrested on allegations of supplying hard drugs.

The arrest comes after The Sun ran a story claiming the 24-year-old had acted as a go-between in a deal to sell cocaine.

The Metropolitan Police force said a 24-year-old woman and a 35-year-old man were arrested "on suspicion of being concerned with the supply of class A drugs" and were being questioned.

Police in Britain do not usually name suspects who have not been charged. The BBC and other major media outlets identified the suspect as Contostavlos, who came to fame with London group N-Dubz.

This is not the first time the former "X Factor" judge has been in headlines for the wrong reasons. Back in March 2012, she admitted to appearing in a sex tape, which leaked online, with her ex-boyfriend DJ Justin Edwards.

Edwards, better known by his stage name MC Ultra, posted the X-rated video online without Contostavlos' permission, she claimed.

She was recently replaced as a judge on TV talent show "X Factor" by Sharon Osbourne.

Contostavlos' rep declined to comment to AP on Tuesday.
