Billie Piper is fond of describing herself as "low-maintenance", but at the press launch for Dr Who's second season the actress was looking decidedly sexy in a combo of a sheer taupe-coloured top and white trousers. Her co-star, gorgeous Scottish actor David Tennant, had likewise gone for casual chic in a trendy jacket and jeans.
The pair regularly stop traffic in Cardiff where most of the series is filmed. Just last month, for an episode set in the 1950s, diversions were placed in streets near the shoot so modern cars weren't caught on camera.
Billie also surprised locals by dressing up in a puffball skirt, zip-up jacket and headband, looking for all the world like an extra out of Grease. Meanwhile, David was sporting sideburns and a Teddy-Boy quiff, which were still in evidence at this week's screening.
The second series got a boost when acting veterans Pauline Collins and Maureen Lipman announced they're joining the show's line-up, along with comedian Peter Kay and Tracy-Ann Oberman, last seen doing time for the murder of Dirty Den in EastEnders.
Pauline portrays Queen Victoria, while Maureen battles the Time Lord as an invading alien who occupies TV sets.
The comedienne was thrilled with her role. "I had to respond to commands such as: 'OK Maureen, now could you give us 15 seconds of having every last drop of energy sucked out of you?'," she enthused. "It was great! This will earn me my entire year's worth of street cred!"
