Guy Ritchie's girlfriend has sparked pregnancy rumors after she was pictured cupping to her stomach at The Dark Knight Rises premiere.

Jacqui Ainsley - who the film director welcomed their first child with last September - arrived on the red carpet in London yesterday showing off her noticeably larger belly.

The 30-year-old model has been dating 43-year-old Guy since April 2010 and they have a son named Rafael. This will be Guy's fourth child. He shares a biological son, Rocco, 11, and an adopted son, David, six, with his ex-wife Madonna. Guy and the singer split in 2008 after eight years of marriage.

Jacqui recently revealed she and her partner planned on expanding their brood: "I'd love more children. Guy and I have always wanted a big family. It's something we planned all along."

Jacqui also revealed how Rocco and David love being big brothers to the baby and always want to help out. "This is the first time I've been a biological mother, but we've got the two big boys and they absolutely dote on Raph. They're always dancing with him and wanting to play with him," she said.
