Some people might think that Sports Illustrated model Kate Upton would be something super sexy for Halloween but the 21-year-old said she doesn't think the holiday should be about showing skin but having fun.

"I'm not sure what I'm going to do for Halloween yet, because I'm going to be working," she told E! News.

Even though she hasn't planned her costume for this year the model did dish on what she's worn in the past telling E! that her past costumes have all been creative.

"In the past, I think my favorite costume was being a bottle of Tabasco," she said. "I felt like it was my most creative moment... it was a lot of fun."

She didn't say exactly what she would be doing on Thursday but she did attend Mike Meldman's Annual Halloween party in Beverly Hills over the weekend with her boyfriend Maksim Chmerkovskiy. Upton wore what looked like a Marie-Antoinette-inspired outfit.  

"I don't think that Halloween is about being too slutty or too sexy," she said. "I think it's about committing to your costume."

Celebrities have already been dressing up and showing off their costumes and it seems like Miley Cyrus has been a popular choice. Hugh Hefner and his wife Crystal Harris attended the annual Playboy Halloween bash as Robin Thicke and Miley Cyrus.

Hugh dressed up in a black and white striped suit while his wife wore a short nude dress, her hair in two high buns and a giant foam finger. Paris Hilton also attended the party as the 20-year-old singer wearing a teddy bear outfit also carrying a giant foam finger.

Comedian Joan Rivers must have gotten the memo because she too dressed up as the "We Can't Stop" singer for a special episode of "Fashion Police." Of course she had to poke fun at Cyrus by wearing a fat version of the bathing suit costume. She also had the foam finger and a giant red tongue hanging out of her mouth.
