Tennant spotted dating television assistant

David Tennant has been spotted apparently dating a young blonde woman who works as an assistant on Doctor Who.

Bethan Britton was seen emerging from the actor's Cardiff apartment, wearing his pyjamas, at 2am on Wednesday, The People reports. Tennant apparently stood in the doorway while she put a parking permit on her car and returned to him.

The report says Tennant met Britton on set at BBC South Wales, where she is a contracts assistant, earlier this year.

They were also seen together at a pub in the Cardiff area last week. An onlooker commented: "They sneaked in and sat in a corner, chatting quietly.

"They kept a low profile but were all over each other, holding hands and giggling like naughty teenagers. They make a lovely couple."

A source added of the relationship: "David has had relationships with actresses but their filming commitments always make it very hard. He loves the fact that Bethan has got a normal job but is still in the TV industry."

Tennant split up with actress Sophia Myles last month.
