Who is that? Former Time Lord David Tennant shared the stage with DJ Christian O'Connell when he played the Virgin Mary in an alternative take on the nativity story.
The actor, soon to star in BBC drama The Spies Of Warsaw, was joined by former Arsenal footballer Ian Wright and singer Newton Faulkner for the performance on O'Connell's Absolute Radio show.
The DJ played Joseph, with Wright starring as a dinosaur midwife, in the performance this morning.
The three wise men were played by a trio of Tennant's fans who won a competition to co-star with him.
Next year will see him team up with another former Doctor Who star when he appears in ITV drama Broadchurch with Arthur Darvill.
Darvill, who played Rory in the sci-fi show, will star as a priest while Tennant plays a detective investigating a murder in a small town.
