Halloween is over, but now comes the best part...finding out what these famous folks came up with for costumes!

Some, like Rupert Grint, Kelly Clarkson and Gwen Stefani came as characters from movies. Kelly Clarkson went as Stewie Griffin and Gwen Stefani when as the girl doll from Toy Story.

We have no idea what Lady Gaga was. We do know that the dress she used could also be used later at a concert. 

One original costume idea was worn by Katy Perry, who went, along with a friend, as a camel. A fun yet hot costume. 

Kellan Lutz and Ashley Green  went to the party in Vegas together in very normal costumes: he as a super hero and she as what we think is a belly dancer.

Miley Cyrus didn't go to much trouble with her costume. She dressed in brown, put on some leather boots and a few red stripes on her face and went as a Native American.
