Here's a nice way to finish off your week: Myleene Klass, a hot and very pregnant British model who stars on the National Lottery show let loose a loud fart during her broadcast Wednesday night on BBC1. Post-fart, she said "Ooh," broke out into a huge grin, and proceeded on with the broadcast. The others in the studio couldn't quite keep from laughing either. Watch the video below.

UPADTE: Video is messed up. Will try to fix.
