An extra who appeared in Tulisa Contostavlos's recent video shoot was found dead in Bournemouth earlier this week.
Reece James, 20 - who was also known by his street name Stylie - was shot in the head in what police believe was a 'pre-planned and targeted' attack.
Reece was filmed in the background of Tulisa's new video on the Church End estate in Harlesden, London this month, although she never met him.
The X Factor judge, 24, came under fire for making a C-shape with her right hand on set - a well-known gang sign in the area - but later insisted that she had no idea of the symbol's connotations.
Reece's friends posted tributes on Twitter last night after it was confirmed that a 22-year-old man had been arrested in connection with his death.
'R.I.P My older g Stylie gone but never forgotten g!' wrote one.
