Matt Smith, Elisabeth Sladen who plays Sarah Jane and Katy Manning who plays Jo
Great news for Doctor Who fans! The new Doctor Matt Smith is to star in The Sarah Jane Adventures!
In two special episodes he'll team up with Sarah Jane and another old companion, Jo Grant, who was in Doctor Who in the 1970s.
The Doctor will need both their help in the alien-busting adventure.
Elisabeth Sladen, who plays Sarah Jane, says: "It's a fantastic script and I can't wait to work with another Doctor and hope Matt has fun with us."
The episodes are hitting our screens in the autumn.
There are other guest stars lined up for the upcoming Sarah Jane series including Strictly Come Dancing contestant Laila Rouass and David Bradley, who played Argus Filch in Harry Potter.
