Miley Cyrus celebrated her birthday over the weekend, and as you might expect it was a fairly tame affair spent at home with a Romantica and a few aul Pringles. 

Ah we're only messing! There was a big cake that was made to look like a pizza and she and her mates got on top of a giant penis thing that bucked around the place. Great craic, sure.

Cake looks good, but the giant mechanical bull that had been re-fashioned into a huge penis was the centerpiece of the evening, without a doubt.

Oh, and she seems to have misplaced her top at some stage. This is OBVIOUSLY NSFW YOU GUYS, but hey, if you're this far in to this article already, you might as well read on.

You can't say she doesn't have a bit of fun anyway.
