Disney star Demi Lovato, who spent three months in rehab, was photographed Tuesday night coming out of Teddy’s club in Hollywood with a controversial sticker on her cellphone.

The sticker reads: “Heroin Killed The Radio Star.”

Some gossip blogs were wondering if  the sticker was a commentary on the death of Amy Winehouse.

But a source close to Demi tells RumorFix that it has nothing to do with Amy, who had fought a heroin and crack addiction for years.

Demi is  just supporting her friend who runs a company called Sober Is Sexy and that’s one of the many pieces of merchandise that they sell.
