Halloween is the spookiest day of the year, but Olivia Culpo is taking it extremely seriously, which may make it hard on Tim Tebow and his vow of celibacy.

The 2012 Miss Universe has been rumored to be romantically linked to the ex-NFL quarterback, and she revealed she has a lot of plans for Halloween this year and will need some costumes for the occasion. Tebow is a devout Christian and has publically said he's saving himself for marriage, but it could be hard for him to control himself when he sees the sexy model in costumes.

But perhaps there's hope for Tebow yet! Culpo was discussing the Donald Trump costume, which is sure to be a popular hit this season, but she said there is way too much emphasis on trying to make dressing up sexy instead of just plain funny.

"What is it with people and Halloween trying to make everything sexy?" she said to E! News. "I mean, you could just be him and it would be pretty hysterical. I think that's a cool one."

That doesn't mean Tebow is off the hook as the model isn't shying away from some of the country's most popular sex symbols. Culpo listed Marilyn Monroe, Audrey Hepburn and Cindy Crawford as potential ideas for easy costumes for the popular partygoers who need multiple ideas to attend the many celebrations for the haunting holiday.

Other ideas Culpo has include Justin Bieber and Hilary Clinton, two options which will definitely help Tebow keep it in his pants.

Then again, Culpo also tossed around the idea of being a cat -- a classic costume and Halloween staple that could prove to be scintillating if she dons it.

"Like I said, the cat is the go-to...It's not like you have to try hard. You can do it in the car," she said. "Everybody wears all black in October usually anyway so you're wearing all black, you have black eyeliner, you just make a cat face and you're good to go."

Tebow may very well be getting a treat this Halloween.
