| Charlie Sheen |
He's been lying low of late, but earlier this year, you couldn't go five minutes without hearing about Charlie Sheen. This Sheen mask, a cigarette and one of his winning T-shirts are all you need to get into character. (But beautiful girls on both arms wouldn't hurt.)

Ryan Reynolds helped make this comic book superhero popular again with the recent film.
The Green Lantern costume is forecast to be a big seller this Halloween. Expect to see a lot of Captain America and Thor as well.

| Lady Gaga |
Everybody's gaga for Gaga.
Spirit Halloween sells two different you can wear to channel the pop diva -- both with some skin showing.

| Katy Perry |
The "Firework" singer is expected to set off sparks for Halloween.
Spirit Halloween is expecting Katy Perry costumes to fly off the shelves.

| Snooki |
Another pop culture favorite is the big-haired Snooki.
In fact, look for most of the "Jersey Shore" cast to show up this Halloween.

| Zombies |
What's Halloween without scary costumes?
With the popularity of the AMC show "The Walking Dead," expect to see plenty of zombies this year.

| Angry Birds |
Move over Mario.
There's another animated favorite expected to make a splash this Halloween. The Angry Birds pigs and birds are pegged to be big sellers this year.

| Smurfs |
Thanks to the current movie, the Smurfs are sure to be another popular animated character this Halloween.
