Nicole Kidman's brainy baby

Nicole Kidman's three-month-old daughter Sunday Rose is already reading the encyclopaedia.

The 41-year-old actress - who welcomed Sunday, her first child with husband Keith Urban, into the world in July - is constantly astounded by her daughter's intelligence.

When asked how Sunday was, Nicole replied: "She is smiling. She is reading the encyclopaedia!"

Nicole, who has recently been shooting scenes for new musical movie 'Nine' in London, also revealed she is thrilled to be back at work and enjoys getting out of the house.

Speaking at Elle magazine's 15th Annual Women in Hollywood event in Los Angeles on Monday (06.10.08), Nicole said: "It's lovely to be part of the celebration. I have been having a baby down in Tennessee so to step back into all of this is a bit of a shock. I think when you have been away from it you appreciate it more so I have a lot of appreciation and gratitude."
