They got married when she was 19 and he is her first husband. They were also in the film Hackers together which is where they meet. He is also married now and thats his son with his current wife. FYI Jude Law was best man at Angie and JLM's wedding. lol just for those who didn't know spicyaroma 7 years I like her sunnies :) Liss1 7 years Yes, he is married. I can't think of his wifes name but she played Shanes wife Mara on The Shield TammyO 7 years Wait, is he married?? Cause then that's it. Sienna will be on top of him soon, she loves her some married men! Man, if I was his wife I would put a stop to this "Friendship" right now! lisa101 7 years She looks great!! and she is great. Hockey-Princess 7 years So how long before we see topless pictures of Sienna locking lips with Johnny Lee? dragenfly75 7 years Johnny is one of Jude Law's best friends, so I'm sure Sienna knew him before they did this show together. jenni5 7 years OK I know I will hear it for this one but if she wants to clean up her image a bit maybe she should stay away from married fathers for a while. ilanac13 7 years i didn't think that he was married to angie - she was married to a few folks but not him i don't think. as for dating sienna - that one i don't think happened either but i could be wrong. anyway, it's nice that they are becoming friends since they spend SO much time together. Asche 7 years Didn't they date at some point or another? Also, he was the one married to Angelina, right?
