Washington, Apr 29 : Avril Lavigne is all set to represent her native Canada by being an ambassador at China's World expo in 2010.

The singer, who was born in Ontario, is much famous in Asia and has even recorded portions of her hit songs in Mandarin.

By traveling to Shanghai, China to represent her home country, she will help bridge the gap between eastern and western cultures.

New Delhi, Dec 14: Avril Lavigne has fired her manager and management company in a bid to revive her flagging career, according to reports.

The ''Girlfriend'' singer's last album, 2007''s "The Best Damn Thing," sold more than 5.4 million copies worldwide, failing to live up to the eight million sales of her previous LP, 2004''s "Under My Skin."

The crooner, apparently, has blamed Nettwerk mogul Terry McBride for her lack of success, reports the China Daily.
