Rob Lowe
Rob Lowe, who revitalised his career by playing an aide to the US president, has had a surprise encounter from a real head of state.

He was rehearsing for his new West End production, A Few Good Men, when someone announced he had a visitor - and it was none other than Tony Blair.

The Prime Minister had apparently turned up to thank Rob for his support after the London bombings, when the Hollywood star had told journalists to encourage Americans to visit London in a show of solidarity.
