Guy Ritchie's girlfriend has sparked pregnancy rumors after flaunting an apparent baby bump at The Dark Knight Rises premiere in London on Wednesday (18Jul12).

Jacqui Ainsley beamed as she cradled her bulging stomach while posing for photographs with the Sherlock Holmes director on the red carpet in Leicester Square.

The couple, who became parents to a son named Rafael last September (11), has yet to officially confirm the happy news, but just last month (Jun12) Jacqui Ainsley shared her plans for a big family in a U.K. interview.

The model told Britain's Grazia magazine, "I'd love more children. Guy and I have always wanted a big family. It's something we planned all along."

Guy Ritchie is also dad to sons Rocco and David from his marriage to pop star Madonna.
