To paraphrase Wikipedia:
Amy Beth Hayes (born 1982) is a Welsh actress. Born in Abergavenny, Wales, but growing up in England, she made her screen debut in the 2008 Doctor Who episode “The Stolen Earth” and the same year she was cast in a lead role in the ITV drama Whatever It Takes. She also starred in the UK Channel 4 comedy-drama Sirens as Sgt. Maxine Fox.
I think she looks a bit like a cross between Christina Applegate and Kristen Bell, no? And there are some awesome NSFW pics of her from Misfits if you Google Image search her name.
She’s stunning!
