With all the hullabaloo over Lindsay Lohan's rehab scuffle, we almost forgot her sister Ali's birthday today. Congrats to the future Betty Ford patient!

Ali Lohan is 17 going on 37. Have an underage drink on her tonight - you know she will be. The (rotten) apple doesn't far from the tree, as they say.

Mason Dash Disick turns one year old today, and his family is celebrating in the only way it knows how: by blogging about the occasion.

Hank Baskett IV turns a year old today, and the little guy really needs your best wishes.

This is a toddler whose dad continues to be cut by professional football teams and whose mother is so desperate for attention that she'll mislead the public about a miscarriage. Pretty tragic stuff.
