The Osbournes Question - Which season?

Hi - I've bought and watched the Osbournes season 1, 2 and 2.5 - My favourite episode which i remember watching on T.V is when a lady wins a competition to live in the Osbourne house for a night - but its not on any of the seasons - can anyone tell me where it is - Is there a season 3 Osbournes because I’ve looked on the internet and can not find anything about it – Thanks
