It’s been reported that X Factor judge Cheryl Cole is being chased to guest-star in the new series of Doctor Who.
The chart-topping solo singer hasn’t yet signed a deal with the sci-fi show but could set to play "a big part", according to The Mirror.
An insider claimed of the shock casting move: "If she can find the time, a part will be written for her."
A BBC spokesperson apparently refused to deny the speculation, and said: "The BBC will not be commenting on casting or storyline speculation for the new series of Doctor Who."
Scottish actor David Tennant, who played the Doctor, is featuring in a number of specials before being replaced in the next series by 27-year-old Matt Smith.
"He's all the things you'd expect, including ancient," head writer Steven Moffat recently revealed, going on to describe the new Doctor as "someone you can't take your eyes off".
It was previously confirmed that Alex Kingston is reprising her role as River Song for a two-part story in the latest series.
