Lily Allen has been condemned for glamorizing guns by wearing a necklace with a machine gun pendant.

The Smile hit-maker - who previously met with London mayor Boris Johnson to outline proposals to reduce knife crime - was photographed wearing the gold pendant on Friday. However the choice of jewelry has outraged anti-violence groups, who have branded Allen "irresponsible".

Lyn Costello, from anti-violence group MAMAA, says: "She is glamorizing the use of guns. It's totally irresponsible. She's a role model and people look up to her. The last thing we want is people looking at her and thinking guns are fashionable."

"I'm really disappointed in her. She had a meeting with the Mayor saying she's worried about knife crime but is she not worried about gun crime too. If she's really worried about violent crime then she shouldn't wear a necklace that promotes guns."
