Blake Lively

'Gossip Girl' star Blake Lively wants to have a comment box in her house so everyone is able to leave constructive criticism for their other family members.

She said: "I think it would be the greatest thing in the world to have a comment box in your home. I want to do it with my kids, and I'm begging my sister to do it with hers. The kids could leave comments on what you could do better, or what the other kids could do better. Like when you leave a comment with management in a restaurant."

Blake and her husband Ryan Reynolds have daughters James, eight; Inez, seven; and Betty, four, and they welcomed a fourth child in February.
