Today, ET spoke to Howard K. Stern and Larry Birkhead as they shared their continued grief for Anna Nicole Smith on what would have been her 40th birthday.

Stern, whose own birthday is tomorrow, told ET, “My only wish is that Anna is celebrating her 40th birthday with Daniel and Howard (Marshall) in heaven and that they are able to experience the beautiful development of Dannielynn from above. Then I know that she would truly be at peace. She was more extraordinary than words can describe. I will never stop loving her.”

Birkhead reveals that he plans to commemorate Anna’s birthday with Dannielynn, “We will have a private family celebration to remember Anna. Time still hasn’t healed the wound of her untimely passing, as she truly was one of a kind. We miss her dearly.”
