Ainsley had sparked rumours of being pregnant Wednesday, when she appeared on the red carpet at the European premiere of her movie 'The Dark Knight Rises' with a baby bump.
"Guy Ritchie and Jacqui Ainsley are thrilled to confirm they are expecting their second child together later this year," Ritchie's spokesman confirmed the news.
This will be the 43-year-old filmmaker's fourth child. He already has a 10-month-old son Raphael with Ainsley, and 11-year-old son Rocco and six-year-old son Davis with ex-wife Madonna.
