Ryan Dorsey has made his first statement since the tragic death of his ex-wife Naya Rivera earlier this month.

The Glee actress drowned while swimming in Lake Piru with her only child by Dorsey, four-year-old son Josey.

Authorities believe that in her final moments, Rivera helped the child back onto the safety of their rented boat before she was pulled under water.

Posting a picture of his ex-wife with Josey on Instagram, Dorsey wrote: "This is so unfair...there's not enough words to express the hole left in everyone's hearts. I can't believe this is life now. I don't know if I'll ever believe it. You were just here... We were just in the back swimming with Josey the day before. Life just isn't fair.

He added: "Life is all about good times and bad times but with Josey it makes the bad a little less so because a part of you will always be with us. He'll never forget where he came from. We miss you. We will always love you. Love you Meep."
