There's been a lot going on for Gwyneth Paltrow and her family since she and Chris Martin announced their separation two weeks ago. Today, though, it was all about their son, Moses, who turned 8 years old! Gwyneth celebrated by sharing an adorable black and white photo of herself smiling big with Moses. She captioned the image, "Moses Bruce Paltrow Martin turns 8 today. We love you!" Happy birthday, Moses!
