Who played the mother of Martin Riggs' child in the "Lethal Weapon" movie franchise?

GiGi2010, it's your loss I think that all 4 movies were pretty good

Player #4905744, She gave birth to his son at the end of #4. The entire scene took almost 10 minutes and Pesci was in it too. In fact, they did a group photo and as the credits started to roll, they did a bunch of outtakes. Obviously you didn't see the movie or at least the ending. She was very pregnant throughout the movie too.

Renee Russo was the wife

Yes..mother of his child. Read!

Wrong answer. She was Riggs lover
