Ireland Baldwin is defending her stepmomma. On Thursday, Alec Baldwin and Kim Basinger's 29-year-old daughter took to Instagram to defend her stepmother Hilaria Baldwin from critics amid her casting in season 34 of Dancing with the Stars: "I wanted to take a second to talk about my step mom @hilariabaldwin. I think if people actually knew her the way I do, they would be quite surprised. This post may come out of left field since I don't post about her or any family members much. I expect misinformed comments and plenty of comments about me only playing nice so I can secure my inheritance.
