Halloween is just around the corner, and to celebrate, KOL got some of today's hottest stars to recall their favorite memories of the dress-up holiday. For instance, mischievous Avril Lavigne would go trick-or-treating down the street, change into a different costume and hit the same houses again for double candy!

Find out what Emma Roberts, Victoria Justice, Miranda Cosgrove, Lucas Grabeel and more had to say about their fave moments in this sweet feature.

Miranda Cosgrove is ready to dish. She's got celebrity crushes just like you, and geeks out for the artists (Avril Lavigne, Natasha Bedingfield) that she got to contribute songs for her new CD 'iCarly: Music From and Inspired by the Hit TV Show.' She loves what she does and manages to stay super down-to-earth while doing it. Find out just how cool the teen star is in her exclusive video interview below, and check out her freshly released album, which is available in stores and on iTunes right now!

Avril Lavigne has postponed six west coast concerts on her "Best Damn Tour" due to acute laryngitis.

"My sincerest apologies to all of my fans," she said in a statement on Saturday. "My intention was to complete the rest of the tour, but tonight at sound check in Anaheim, I realized this wasn't possible.

"Even though I have been resting my voice for days," she continued, "when I tried to sing nothing came out."

If you had tickets to her shows in Anaheim, Universal City, Santa Barbara, San Jose, Spokane or Everett, refunds will be available at point of purchase today.

She started out as skater girl singer who didn't care about manners or impressing anyone with her looks. However, over the years, Avril Lavigne has traded in her Converse for pumps and her punk ways for poise.
