Jerry O'Connell sings rap songs to his babies when he puts them to bed.

The actor - who has eight-month-old twin daughters Charlie and Dolly with wife Rebecca Romijn - loves sending his girls to sleep with toned-down versions of some of his favourite tunes.

He said: "At bedtime I softly sing rap songs by guys like Slick Rick or Biggie Smalls - but without the curse words. I have favorite little bedtime nighties I put them in which say, 'I love Project Runway.' "

Jerry admits he is always learning about fatherhood and especially enjoys dressing his daughters in pretty clothes.

He told People magazine: "I grew up with all boys in my family, where there was no place for girlie stuff. But it's amazing to walk into my house now. Everything is pink!

"When we first brought Dolly and Charlie home, Rebecca would say, 'We're going out, let's put them in this dress. At first I thought it was impractical. They're going to poop and throw up in it anyway. What's the point? But now I understand dressing girls.

"Now that they've got a bit more hair, I can experiment. I can do mini-pigtails on Charlie, and on Dolly I can get barrettes in her hair."
