But Millie and Hugo back in MIC? URGHHH, getalife
It's the same with all of them. They get a bit of reality TV fame, it goes to their head, they think they are bigger than the show. They think they can leave and see it as a launch pad to greater fame failing to realise that they aren't actors, comedians, performers or tv presenters and THEY HAVE NO TALENT.
So it comes as a bit of a shock when no one is really that interested and in order to stay in the papers/ on the fame red carpet circuit they need ....er .... to do something. After a few Katie Price/Kelly Brook attempts at staying current via various "relationships" they realise actually they are nothing without the show and come back.
The prime example of this is Ollie. Read the interviews he gave when he left. It's hilarious. And back he came.
I'm fully expecting Spencer to have a nervous breakdown once he realises how properly transient his fame is without MIC. He'll probably be dating Kelly Brooke in a minute.
