The brother of former X Factor winner Alexandra Burke is a drug dealer, according to reports.

Aaron Burke, 18, deals in drugs including cocaine and claims to supply the drug to celebrity clients, reports The Sun.

The newspaper apparently caught him on video dealing cocaine in Islington, North London last week.

The 18-year-old, who has twice auditioned for the X Factor, is said to have claimed that his clients include a member of a boyband and a rapper.

Burke is said to have no knowledge that her brother is an alleged drug dealer. The singer won the talent show in 2008.
