Trisha GoddardTrisha GoddardTelly chat queen Trish Goddard is to star in Doctor Who... as herself.

She's best known for flushing out love rats and cheats, so how will Trisha fare against the Daleks?

Luckily, she won't have to find out.

In the new series, the Time Lord - played by David Tennant - will discover that Earth is overrun by ghosts, before stumbling upon Trisha's show.

An insider told the Daily Mirror: "It's an episode called I'm In Love With A Ghost. Trisha asks, 'Can you trust him if he's always appearing and disappearing?' It's hilarious."

Trisha, 48, is a life-long fan of Doctor Who, as she reveals: "Ever since I was a child I've liked to be scared.

But the Norwich-based presenter, who now hosts her agony-aunt show on Five, admits she and hubby Peter actually prefer Star Trek.

Last year's series of Doctor Who also parodied TV shows when the Time Lord went on Big Brother. And his companion Rose - played by actress Billie Piper - appeared on the Weakest Link.
