Doctor Who‘s sidekick finds herself pregnant in an upcoming episode – but who’s the daddy?

Amy Pond – played by actress Karen Gillan – is seen with a bump in the episode, Amy’s Choice, to be screened on Saturday, May 15.

The episode is partly set five years into Amy and The Doctor’s future, when she is pregnant.

Fans of the hit Saturday night show will soon see the arrival of her fiance, Rory (Arthur Darvill).

Show bosses are keeping tight-lipped about the pregnancy – but are promising viewers will get an insight into how the apparent new addition occurred.

The episode will also feature the Tardis parking in a flowerbed and The Doctor (Matt Smith) driving a camper van.

A programme source said: “Viewers will have to wait and see how the pregnancy came about, but as always with Doctor Who, things are not always as they appear.”
