It's not going well for Doctor Who - after another big name decides to quit the show.
This time, it's the glamorous Billie Piper - who plays the Doctor's sidekick Rose Tyler - who's moving on.
It seems that the TV series has helped further her acting career and now she wants to get involved in other projects.
A BBC insider told The Sun: "Billie's really proved herself as an actress in Doctor Who and she's been bombarded with offers of work both in England and in America."
"Billie will feature in some of the second series. But her character Rose won't be the Doctor Who companion at the end of it.
"It's a nine-month hard slog filming, Chris and Billie were knackered.
It's claimed that she could appear in just three episodes of the new series, which begins filming in July, but programme bosses hope she'll stick around for seven.
David Tennant is taking over from Christopher Eccleston for the new series, after Chris made the decision to quit at the end of March.
