Pamela Bach kicked rumours that she’ll be appearing on Celebrity Big Brother up a level today, when she arrived in London.

The 47 year old American actress – who was once married to Britain’s Got Talent judge David Hasselhoff – was recently reported to have signed a deal with Endemol bosses, which would see her entering the Elstree residence later this week, in the hope that she’d spill the beans on her tumultuous relationship with the former Baywatch star.

The celebrity version of the reality TV show will launch on Channel 5 this Thursday and it looks like the former Sirens actress may be on the lineup, as she was pictured shopping in Mayfair with a mystery man on her arm earlier today.

Show bosses are trying to play their cards close to their chests and have refused to confirm any names for the new series, however it seems just too coincidental that the blonde beauty would make a rare trip to the UK, three days before the CBB launch and not be planning to take part.

Other American celebrities rumoured to be entering the Big Brother house this week are Bobby Brown, Pamela Anderson and Tara Reid. For the full list of reported housemates click here and make sure you check out our exclusive pictures of the house, taken during our tour today!
