The 'Girlfriend' singer will showcase the latest collection for her Abbey Dawn clothing range at the prestigious event next month
According to a press release, the event - which will take place on September 12 at the city's Style 360-Metropolitan Pavilion - will be "a high-energy runway fashion show".
The ladies' line will include dresses, denim, skirts, footwear, handbags, wallets, purses and eyewear.
Earlier this year, Avril said her fashion tastes have grown more sophisticated over time.
The 'What The Hell' hitmaker used to be famed for her rock chick look but has now started to wear dresses and heels as her style has matured over the years.
The 26-year-old star said: "When I was younger, I dressed skater and had that whole thing going on. But as I grew up, I eventually started wearing heels and dresses. Over time, fashion choices change. Now that I'm older and have a fashion line, I'm more into fashion.
"I like to dress with rock 'n' roll elements and be casual. I like jeans with rips and skulls, but now I wear more flattering pieces. I would never have worn heels or tight trousers before, or dresses. Today, though, I enjoy it. I've grown up."
