Avril Lavigne's concert apology

Avril Lavigne has apologised to fans for cancelling a concert.

Fans were left fuming after her San Diego show was cancelled last Wednesday (30.04.08) because the star was diagnosed with acute laryngitis.

Lavigne - has also had to pull out of a performance on the hugely popular 'Tonight with Jay Leno' US TV show - says touring has taken its toll on her health.

The 23-year-old singer wrote on her official blog: "I have been on the road for 60 days straight. I just played four shows in a row in Texas (which is a lot for the vocals) and woke up in Las Vegas on Tuesday with no voice. My voice is so shot. We drove home yesterday and I went to my throat doctor. He said I have acute laryngitis.

"So, um, yeah, that sux [sic]. I'm at home resting my voice for two days and hope to be back out soon. Thank you for understanding. And once again, I sincerely apologise."

Fans were not told the concert had been called off until they arrived at the venue. The show, part of the singer's 'The Best Damn Tour', will now be re-scheduled to a later date.

The 'Sk8r Boi' singer's 40-date US tour has apparently suffered from poor ticket sales and disappointing reviews.

Lavigne is due to tour Europe at the end of May and June.
