Lily Allen broke down in tears on stage at the weekend after suffering from crippling back pain. The singer had revealed on Twitter earlier in the day that she’d hurt her back in a fall, saying: “Fell over badly last night and I've really f***** my back up. Just had an injection in my bum. How am I gonna get through tonight's gig? The 24 year-old was later seen at the gig in Helsinki, Finland wiping tears from her heavily made up eyes, and told the crowd: “I feel a bit emotional tonight and if I cry it's not because of you but because of me.” Poor ill Lil.
