The actress was last seen helping to save the Time Lord’s life in Doctor Who series seven finale The Name of the Doctor. Her future on the show was left open-ended, with fans currently unsure if she will be returning for the 50th anniversary special in November.
Whether any such revelations will be forthcoming tonight remains to be seen but hosts Alex Jones and Matt Baker are unlikely to let Kingston leave the One Show sofa without discussing Doctor Who and at least speculating on what might be next for River Song – and who might be set to replace Matt Smith when he leaves Doctor Who at the end of the year.
Other guests tonight include singer Sharleen Spiteri and author Philippa Gregory, whose historical novel The White Queen has been turned into a BBC1 drama series.
The One Show is at 7pm tonight on BBC1
