It has been announced that London-born actress Freema Agyeman will star opposite David Tennant in the third series of the new 'Doctor Who'.
27-year-old Agyeman will play brand new character Martha Jones in the third series, replacing Billie Piper (Rose) as the Doctor's companion.
Agyeman played a character called Adeola in last Saturday's episode of the current series.
Commenting on her casting, the show's Executive Producer and Writer, Russell T Davies, said: "The search for a new companion had been underway for some time when I first saw Freema Agyeman, she had come in to audition for the part of Adeola in series two.
"Watching her during filming confirmed what an exciting new talent she was, so under cover of darkness we called her back in to audition with David for the role of the new companion.
"It was an immediate and sensational combination, and her range, presence and charm blew us all away."
"Auditioning with David in secret down in Cardiff was unbelievable," said Agyeman, "but I never in my wildest dreams thought I'd actually become the new companion."
She continued: "Billie rightfully built up an amazing fan base and she will be missed, but I hope the fans are willing to go on new adventures with me."
'Doctor Who' star David Tennant said: "Freema was a joy to work with in episode 12 of the current series. She is not only very talented and very beautiful, she's great fun and I'm delighted she's coming on board the TARDIS full time."
The new series of 'Doctor Who' will begin shooting in Cardiff this summer, with a Christmas special, which won't star Agyeman, also in the works.
