UK composer Paul Mealor has composed a royal lullaby fit for a king ... or queen.
Mealor, who wrote music for Kate Middleton and Prince William's wedding, has penned a lullaby for the pair's firstborn child, due to be born in mid-July.
Classical artist Hayley Westenra will record the song, sweetly titled "Sleep On."
While recent speculation is that Kate is expecting a boy (Prince Harry believes this), the baby will be in line to inherit the throne after William either way.
It's only fitting that he or she will have a signature lullaby.
