Jennifer Lopez and Casper Smart are currently on tour in Germany, but in the spirit of Halloween they decided to channel their inner flower child and don bell bottoms and flowers in their hair as '60's hippies!

Leave it up to RiRi to change clothes in the middle of her own party!

Rihanna hosted a Halloween party at Greystone Manor in Hollywood last night, and the "Diamonds" singer walked the red carpet in a demure black dress before changing into a green veil and costume. Could she have been paying homage to her favorite past time?

Once inside, the Barbadian beauty partied with rumored on-again boyfriend Chris Brown, who was dressed as a Taliban soldier, and Basketball Wives star Evelyn Lozada.

Later in the night, Katy Perry's bestie was crowned the Queen of Halloween!

It must be nice to be the pop princess!

Riddle me this, riddle me that ... which family rocks Halloween costumes that are beyond phat? Oh, yeah ... the Kardashians!

Kim Kardashian put on her sexiest Catwoman costume while Kourtney showed off her post-baby bod in a skintight Batgirl get-up for a party at Liv Nightclub in Miami.

This group knows how to work it. Too bad Kris Jenner didn't show up as Wonder Woman.

Always one to love grabbing attention, Chris Brown arrived at Greystone Manor dressed in what appeared to be a member of the Taliban.

The controversial costume certainly made a statement and raised more than a few eyebrows.

Do you think this is an appropriate look for Halloween?

Can this family be any cuter?!

After tying the knot, giving birth to a baby vampire and coming back from the dead with a set of fangs, it's time for Bella to settle down with her husband Edward Cullen, so her sister-in-law Alice is sweet enough to take them to their new home in this just-released clip from Breaking Dawn - Part Two. We get a peek at their cottage, and of course the last scene shows the lovebirds standing in front of a bed, with Edward kissing Bella's neck and telling her, “It’s not intended for sleep."

And the other day, this new clip of Bella getting vampire lessons from the Cullens hit the web as well ... check it out!
