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. 

Dakota Fanning spent Halloween in a weird way : doing the splits, jumps and cart-wheels.

The 15-year-old actress hasn't gone crazy, she just a cheerleader foir her school's team, The Vikings of North Hollywood, and a few days ago they named her 'Princess of the Cheerleaders'. 

 Dakota took advantage of this day to spend it doing one of her favorite hobbies with her classmates. Soon she won't have times fo any of this because she will be on the road promoting New Moon. 

Trace Cyrus, Miley's brother, has uploaded some photos from his sister's concert onto Twitter. 

Trace uses his Twitter and asks his fans to do the same. A few days ao he asked fans to share their favorite concert photos with him so that he could put them on Twitter. 

Trace Cyrus is the lead for the band the Metro Station and he'll be participating in a few of Miley's concerts. Trace also shared another family secret with fans. He said that Miley's little sister is the one who taught her how to jump up and down on stage like a crazy person. 

Hybrids are plants or animals that are the result of mixing two different species. These creatures are strange and rare, and are usually the result of man toying with nature.

Hybrid animals take the best traits from their mother and father, and that is why they are created to increase productivity.

Some of the weirdest hybrids out there are ones like the Liger, which is a cross between a lion and a tiger. The result is a lion with stripes. A liger is bigger than a lion because it doesn't have the gene that limits growth. This is the biggest feline in the world! It can be up to 12 feet long!

Another strange one is the Tigon, which is a cross between a male tiger and female lion. In this case, the Tidron is small, because it haws twice as much of the gene that stops growth. These animals were raised and created in captivity and you would never see them in the wild (tigers live in Africa and Asia).

Some other cool hybrids are the Zebra-horse, the Leopion, which is a cross between a female lion and a leopard and the Bengali, which is a mix of house cat and bengali wildcat.
