Britney Spears has written a lullaby for baby son Sean Preston.
The singer, who is currently pregnant with her second child with husband Kevin Federline, has penned the loving ode to the tot and reportedly sings it to him before he goes to sleep at night.
Britney is so pleased with her composition that she is hoping to put the song on her long-awaited new album.
A source said, "She wanted to write Sean a song to show how much she means to her."
As Britney prepares for the birth of her second child, husband Kevin is gearing up to debut his first single at America's Teen Choice Awards.
The fledgling rapper will close the ceremony, taking place next month, by performing 'Lose Control'.
The song, taken from Kevin's upcoming album 'Playing With Fire', is set to be his first official release. Jessica Simpson and rumored boyfriend Dane Cook are hosting this year's Teen Choice Awards, which recognize the most popular celebrities as voted for by millions of youngsters.
