The 'Girlfriend' singer was given the tip during a photo shoot and says she now always uses it if she ever has trouble getting into her favourite pair of heels.
She advised: "If you can't get your foot in a high heel, put body lotion all over your foot and it'll slide in no problem - I picked up this tip on photo shoots."
Avril is famed for long-flowing locks and achieve them, she recommends only washing hair every other day to give it a chance to breathe.
She told Now magazine: "I wash my hair every other day as I don't think it's good to wash your hair daily and I always leave in my conditioner for an hour. I also like to use hairspray and serum."
Avril recently launched her new fragrance, Forbidden Rose, and says she thinks it's the perfect scent for any young woman.
The 25-year-old star said: "I've called it Forbidden Rose and the tag line is 'Dare to Discover', which resembles me and where I'm at style-wise. It's young, fresh and floral and the kind of fragrance you can wear during the day and evening.
"This is the first fragrance I've worn all the time and even my friends and sister love it - so much so that we all wear it at the same timeto smell the same."
