You all know my sisters are huge fans of dressing up. Whether it's for a red carpet event, a photoshoot or dinner with family and friends we love to get all glammed up, so naturally Halloween is one of our favorite holidays! This year we have teamed up with Celebuzz to do a super fun Halloween costume contest, Costuming Up with the Kardashians.

All you have to do is upload your sexiest, most unique costume as a comment on the contest page and right after Halloween, Kourtney, Khloe and I will choose three winners who will receive some awesome prizes!

Head over to the contest page now to enter!

I decided to be Wonder Woman after all! I really think she is sexy and powerful and we should all feel like Wonder Woman every day! I went to Trashy Lingerie, which is the craziest sexy costume store in the world! They had everything from the boots to all the accessories and corset! It was perfect!

That's right, last night I threw a Halloween party at the Hotel Sofitel in Los Angeles at the Rose Bar inside! All of my Dancing With The Stars friends came out to support! Everyone from Lance Bass, Karina and Max, Jeff Ross, Warren Sapp (his costume was priceless, his Paso Doble outfit), Kym Johnson, Derek Hough, and Cheryl (who got ready with me at my place before the party!)!

My mom and Lara Spencer came together and how amazing were Brittny and her mom Lisa's vampire outfits!? Lisa did all the makeup herself!

Kourtney and Khloe are in Mexico and sooo sad they couldn't make it! The Dash Dolls, and Smooch Dolls all came as Alice in Wonderland-themed sexpots! I love you Lily, Sydney and Roya!

Troy Jensen did my hair and makeup and we took some fabulous pictures! He dressed up as Clark Kent!!!!

My Web producer Meriah Doty also showed up!

It was a great time. Happy Halloween, everyone!!!!
