Doctor Who fans have speculated over David Tennant's wife Georgia returning to Doctor Who and reprising her role as Jenny.
Georgia, 37, first played the role of Jenny in The Doctor's Daughter in 2008 and in various Big Finish audio productions.
Now fans of the show have come up with a theory around her return and think the actress, who has been married to David Tennant since 2011, has dropped a 'hint'.
