Daniel Radcliffe's new medic role

Daniel Radcliffe has signed up to play a doctor in a new TV drama.

The Woman In Black and Harry Potter actor will star alongside Mad Men's Jon Hamm in a four-part series about Russian doctors after the First World War, The Sun reported.

Both actors will play the same character in the Sky Arts drama, with Daniel playing the doctor in his younger years.

A source told The Sun: "This is a great role for Daniel and he's pretty excited about the prospect of working with Jon."

US star Jon - who plays Mad Men advertising executive Don Draper - will also narrate the story.

Daniel's next film is set to be Kill Your Darlings, directed by John Krokidas.

The actor is set to play Allen Ginsberg in the true story of a murder committed by one of the American poet's friends.

Could Miley, Demi or Avril become an 'X Factor' judge?

We know that Simon Cowell is looking for a few good women to join his "X Factor" judges' table, and there's a fresh batch of rumored names being added to the mix.

According to reports, the reality show king is said to be eyeing Avril Lavigne, Miley Cyrus, Gwen Stefani and Demi Lovato for one of the open judging positions, in addition to also reportedly trying to seal a deal with Britney Spears.

E! reports that Cyrus is among the stars in consideration to join Cowell and L.A. Reid on the star-studded panel, but a source tells the site that she hasn’t received an official offer.

But she may have some competition for it: the Hollywood Reporter suggests Lovato is already in final negotiations to star on the show.

Spears, meanwhile, is thought by some to be a shoo-in for the third seat with a reported $15 million offer - although an official announcement has not yet been made.

Spears is the last holdover from the earlier round of names that the media batted about as potential "X Factor" judges, following the dismissal of season 1 personalities Nicole Scherzinger and Paula Abdul.

Cowell's got a little time to see who wins the battle of the divas though: the second season of the talent competition is not expected to kick off until September.
