Guy Ritchie has named his youngest son Rafael.
The 'Sherlock Holmes: A Game of Shadows' director and his model girlfriend, Jacqui Ainsley welcomed their first child together last September, but have only now revealed his name.
Jacqui told the Sunday Mirror newspaper: ''We thought Raffie Ritchie sounded really cute when shortened. His older brother, Rocco, helped choose the name - we were throwing ideas out there as a family and it stuck from early on.''
Guy, 43, has Rocco, 11, and adopted son David, six, from his marriage to singer Madonna, who he divorced in 2008. Raphael is Jacqui's first child.
Jacqui, 30, added: ''He has two great brothers which is really lovely. I'm the happiest girl in the world and loving motherhood.''
Rocco took centre stage earlier this week when he appeared with his Madonna on the opening night of her MDNA tour in Tel Aviv, Israel. He was seen dancing on stage and had three costume changes - including a monk's outfit - as part of the performance.
When asked if she teaches him her dance moves, Madonna said: ''No, he shows them to me! But I'm pretty bad. My son loves breakdance.''
Meanwhile, Guy is rumoured to have signed up to direct a new version of pirate adventure 'Treasure Island'.
