British pop star Lily Allen is battling a nasty bout of flu while on tour in Australia.

The Smile singer fell sick after arriving in the country ahead of her shows, and she blames her health woes on her gruelling travel schedule which took her to gigs in three different countries in three days over the weekend (19-20Jul14).

She tells Australia's Fairfax Media, "I played at Latitude Festival (in England) on Friday, Benicassim (in Spain) on Saturday, and a French festival on Sunday and then got on a plane to Australia... I don't know if it's advisable to do that kind of travel."

Allen has since been complaining about her ill health in a series of posts on her Twitter.com page, writing, "Sneezing. A lot... Flu... Might die... My antibiotic tablet has left an awful taste lingering in my mouth."

However, her tour kicked off as scheduled in Melbourne on Thursday night (24Jul14).
