The couple, who welcomed their son Raphael into the world in September, have said they are "thrilled" to be expecting their second child together.
Model Jacqui had set tongues wagging last night after cupping her rounded stomach on the red carpet in Leicester Square.
A spokesman for Guy has since told Reveal: "Guy Ritchie and Jacqui Ainsley are thrilled to confirm they are expecting their second child together later this year."
The couple were all smiles as they posed for pictures at the high profile event.
Dressed in a loose-fitting LBD, Jacqui looked glowing as film director Guy placed his arm around her waist.
Just weeks ago, Jacqui had admitted: "I'd love more children. Guy and I have always wanted a big family. It's something we planned all along."
