Congratulations could be in order for Keira Knightley, as she is rumoured to be pregnant with her first child.

The Imitation Game star – who married Klaxons rocker James Righton last year – is more than three months along so will be hearing the pitter patter of tiny feet in 2015, according to The New York Post’s Page Six.

The actress, 29, has been at the centre of baby rumours for some weeks and the speculation was fuelled at the weekend when she apparently avoided alcohol at the Moët British Independent Film Awards.

Keira looked her stunning self on the red carpet but some people have pointed out that her fur-trimmed metallic dress was looser than her normal tailored styles.

The couple have not commented on the pregnancy rumours but Page Six claims that the happy news has been confirmed by multiple sources.
