Downey, Jr.'s producer wife Susan gave birth to Exton Elias Downey, the couple's first child, in Los Angeles on 7 February (12), but the Brit had no idea - and was caught off-guard when he was asked about his thoughts on the newborn while promoting the movie's sequel on Thursday (16Feb12).
A surprised Law replied, "I didn’t know the baby was born. Is that true?! Wow! I didn’t know. I knew it was expected. When? Am I late? How long ago? Last week? I feel terrible."
Downey, Jr., who also has an 18-year-old son named Indio from a previous relationship, did not attend the premiere of Sherlock Holmes: A Game of Shadows in Tokyo.
