Rachel was finally preparing to go to sleep for the first time in the house in the early of hours of this morning (07.06.08).
The excitable former child actress has not been to bed since entering 'Big Brother' on Thursday night (04.06.08) because she "might miss all the fun".
But the Miss Wales runner-up - who acted in film 'Night Train To Venice' with Hugh Grant when she was eight-years-old - finally had to give in to tiredness.
Before heading to bed, Rachel told her fellow housemates it was the sheer excitement of being in the house that had kept her awake. Cocky P.E. teaching student Dale agreed the adrenalin could keep him awake no matter how tired he was but Sierra Leone-born Sylvia said she needs her sleep.
But the sleeping habits of the contestants are already causing friction.
Jennifer, Sylvia and Darnell - who stayed up chatting into the early hours - are all fed up with the housemates who moan about them entering the bedroom when they already asleep.
Jennifer said: "Hello, why are you asleep? This is the Big Brother house!"
