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 (18.07.12) 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.

She said: ''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.

She said: ''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.''
