That's one way to wish a friend a happy birthday! On Sunday, Chrissy Teigen took to Instagram with a special message for one of her pals.
"HAPPY BIRTHDAY @MARISAMXO!!!!" she captioned a nude photo of herself.
In the racy pic, Teigen's hubby, John Legend, is sitting (fully clothed) in a chair, as she sits on the back of the chair facing away from the camera with her long hair flowing down her back.
In the pic, the supermodel is covering her chest with her arms.
Teigen looks fit and fab just six months after welcoming daughter Luna. The first-time mom is thrilled to see her little girl celebrating some big milestones.
"She had her first bites of a baby cereal. It's so exciting for me. Obviously I love food – I cannot wait to cook for her!" Teigen recently gushed to ET.
