Updated 12.27 Wed Aug 01 2007

Kylie Minogue has proved her acting skills are still up to scratch since her days in Neighbours.

The pop star was filming her part as a waitress for the Christmas Special of Doctor Who, when a pensioner mistook her for the real thing and asked her for a cup of tea.

But instead of having a 'do you know who I am?' moment, the Aussie star apparently found the whole thing quite funny.

The 39-year-old plays Astrid in the one-off episode, set aboard the Titanic.

The show will feature a number of celebrity cameos to appear alongside actor David Tennant who plays the title role.

The episode, Voyage Of The Damned, began filming in Cardiff and the story follows on from the ending of the third series, when viewers saw the Titanic ship crash through the walls of the Tardis.

The fourth series of Doctor Who will feature comedienne Catherine Tate as an assistant.
