Pamela Anderson Has Final Surprise For 'Big Brother' Housemates

PRESS ASSOCIATION -- Pamela Anderson is set to drop a final bombshell on the Big Brother house before she leaves.

The 44-year-old Baywatch star will pick a fourth golden housemate before she departs, but after learning they have won immunity from eviction this fourth housemate will be told they must pay the price by choosing one of the other golden housemates to lose their status.

Model Heaven Afrika, student Aden Theobold and 19-year-old blonde Maisy James have all be named golden housemates.

The fourth golden housemate must choose which of the three will lose their immunity from eviction.

Meanwhile, housemate Mark Henderson, 28, asked Pamela if she would have sex with him, but she let him down gently telling him he was too young for her.

Mark consoled himself by cuddling up in bed with glamour girl Louise Cliffe and 28-year-old Rebeckah and his teddy bear.
