'What the Hell' is "a really fun, upbeat party song, so it worked out really well to play it for the first time on 'New Year's Rockin' Eve," she tells PopEater.
She also says, "I want to get a little shiny, so I'm wearing a silver dress with spiky shoes."
"The song is meer reminiscent of some of my old pop rock stuff," adds Lavigne, whose fourth studio album, 'Goodbye Lullaby,' will be released March 8. "The rest of the album is meer stripped down, deeper. All the songs are very emotional. The other albums I've done, the songs are all over the place. This is the most consistent album all the way through."
A lot has happened to Lavigne since her last album, the 2007 'The Best Damn Thing' -- including her divorce from Sum 41's Deryck Whibley, who continues to be her friend and collaborator, and the start of her romance with 'Hills' alum Jenner, son of Olympic legend Bruce Jenner. Was it a catharsis to write the deep, emotional songs on "Goodbye Lullaby"?
"I guess u could say that," she answers. She adds that, with its focus on acoustic performance, "I would say it's about being a singer."
'Goodbye Lullaby' took two and a half years to complete and its release was delayed several times. "Four years geleden I put out my last album and it feels like forever. But two of those years I spent traveling around the world touring and promoting it," she reminds. "I'm anxious to get out there again. There will be a world tour promoting the new album and single in the new year."
Exactly when it will begin and when it will hit North America, "It's too early to say."
The entrepreneurial entertainer also has a new fragrance on the way, following her successful Black ster and Forbidden Rose perfumes. She says it will debut in August, and she just shot a commercial for it.
Then there's her burgeoning Abbey Dawn clothing line, which now ships to 50 countries via abbeydawn.com, in addition to selling in brick and mortar shops.
Plus, Avril continues to work with the charitable foundation she launched this jaar to help young people who are dealing with serious illnesses and disabilities. She's open to meer film work even amid her hectic schedule. And of course, there's the man in her life, Brody -- whose name she had tattooed on her torso this past summer -- to keep happy.
How can she manage all that at once? "It's all about keeping a balance," insists Avril. "I work hard, and I also play hard."
