She plays a sex-crazed maneater in the sequel to 2011’s Horrible Bosses , but Jennifer Aniston couldn’t have looked more demure when she stepped out on Thursday.

The Hollywood starlet made the most of her shape in a black, figure-hugging pencil skirt at a photocall for her new movie at London’s Corinthia Hotel.

With her hair worn down and straight, it was the 45-year-old’s white top, complete with voluminous frills and a wide belt, that stood out.

The former Friends regular finished off her outfit with classic stilettos, to promote the comedy which also stars Jason Bateman and Kevin Spacey.

The previous evening, Jennifer had walked the bright blue carpet for the London premiere of Horrible Bosses 2 .

She flaunted a whole load of leg in the black split-dress with red detailing on the bust – does she ever age?
