Play our omg! Twitter Festive Fittie Advent Calendar game, and win a whole host of prizes!

The countdown to Christmas has officially begun and here at omg! we are more than a little bit excited.

So to celebrate this festive occasion we are offering YOU the chance to win a whole host of goodies over the next 24 days.

Now you may have noticed that the omg! ladies are somewhat obsessed with hot male celebrities so we have devised an advent calendar with a twist.

Ladies and Gentlemen we give you: The Festive Fittie Advent Calendar game.

So here is what you need to do:

1. If you don't already, follow our official Twitter account @YahooOmgUk

2. Check the account over the next 24 days to be in with a chance of winning a mystery prize.

3. We will be posting a picture of a male celeb body part and it's your job to guess who the celebrity is in order to win a mystery prize each day of advent, right up until Christmas Day.

4. Simply tweet us your answer with #festivefittie at the end.

5. The first person to correctly identify that day's festive fittie will then win a mystery prize from our Santa's sack of goodies.

Good luck and get guessing to be in with a chance of winning!
