Update: Jon’s rep tells People that Brighton was 6 lbs, 13 oz, and was 18.5 inches long.

Originally posted August 30th: When we reported back in May that actor/director Jon Favreau, 39, and his physcian wife Joya were expecting a third child, we didn’t know it would be so soon! However, Jon has posted a blog on his MySpace announcing the arrival of daughter Brighton Rose on Tuesday evening. Jon writes, "I just had a baby. Last night I had my third kid. Her name is Brighton Rose Favreau and she’s doing great." Brighton joins siblings Max, 5, and Madelaine, 3.
