Does Dr. Huxtable know about this? Here's a photo of a pregnant Lisa Bonet and her daughter, Zoe Kravitz, walking around NYC recently. And, no, that's not a watermelon under Lisa's shirt -- though tis the season. (For watermelon... not wearing them under your clothing.) That is apparently a baby bump. Apparently this is her third child. (Raise your hand if you knew about the second child. Me either!) The likely daddy is her longtime boyfriend Jason Momoa. I bet if she hadn't quit the Cosby Show then we would have known she was pregnant the day she took the test. She totally dropped out of sight after that show... not that that's a bad thing.
