Doctor Who's Jenna-Louise Coleman goes topless in BBC4 drama 'Room At The Top'

London: Doctor Who's sidekick Jenna-Louise Coleman has peeled off for a brand new BBC4 drama.

The actress, who plays Oswin Oswald in the sci-fi series, was last night seen baring her breasts in two-part series Room At The Top.  The 26-year-old stars as posh totty Susan Brown in the adaptation of John Braine's novel of the same name.

It follows the rise of ambitious social climber Joe Lampton, played by Matthew McNulty, in post-war Britain.

 Joe sets his sights on Susan, the young daughter of a local council big-wig who is very much out of his league, as his ticket to the top.

But until he wins her over he amuses himself with married lover Alice Aisgill (Maxine Peake).

The series concludes tonight at 9pm.
