Keira Knightley has stepped up her romance with her musician boyfriend James Righton by moving him into her London home, according to a U.K. report.

The Hollywood actress, 26, has been dating the Klaxons rocker since early last year, following her split from her partner of five years, Pride & Prejudice co-star Rupert Friend.

Righton has now moved into Knightley's house in east London and they are considering getting a puppy together, reports to Britain's Mail on Sunday.

A source tells the publication, "Keira suggested the idea and he moved his stuff in a couple of weeks ago. They want to get a puppy. It's all pretty serious."
