Avril Lavigne, currently on the European leg of her Black Star tour, was late tonight to a London concert due to a security incident that she later wrote made her “scared for (her) life”.

In addition to hitting the stage more than a half hour late, the singer eventually lost her voice with a few songs still remaining in her set list.  Concert goers posted that her voice continued to crack during her hit song “Complicated”, which eventually led Lavigne to give up entirely – holding the microphone towards the crowd, who enthusiastically picked up where she left off and completed the song.

Although some reports indicated the songstress became emotional as the concert wound down, others – including fans in the front row – wrote that she seemed in good spirits and appeared bemused, though frustrated, with her fading voice.

UPDATE: Avril Bandaids, the top Avril Lavigne fan site, has posted amateur videos from tonight’s concert, including this video by Youtube user “Popgoer” showing Avril Lavigne good-naturedly struggle through her final song, “Complicated”, with help from the audience.

Lavigne finally admitted to fans who packed the HMV Hammersmith Apollo that she had had a bad day and couldn’t sing any longer before leaving the stage.

The singer’s Twitter posts before and after the show revealed an unspecified security incident had delayed her arrival, and she most recently posted to Facebook that “Shortly before my show tonight, there was a breach in security and now the police are handling (it)”.

Fans were united in expressing condolences and well wishes to the star online, and “Feel better Avril” became a worldwide trending term on Twitter – which the singer acknowledged and thanked fans for on her own Twitter account.
