Nicole Kidman's Teenage Daughters: The Closet Chaos Chronicles

Nicole Kidman's teenage daughters, Sunday Rose, 16, and Faith Margaret, 13, have discovered a new favorite pastime: raiding their mother's closet.

They go into my closet and it looks like a bomb's hit it, Kidman, 57, joked to Entertainment Tonight on Wednesday.

The actress, who shares her daughters with husband Keith Urban, said her girls are very tall like her, making it easy for them to share clothes.

While the teens still prefer basics, Kidman said it's only a matter of time before they start trying on her designer duds.

In fact, Sunday has already made her debut in the high-fashion world, joining her mom at Paris Fashion Week in June.

The mother-daughter duo rocked up to the Balenciaga show in coordinating black dresses.

Kidman said the event was Sunday's first fashion show, despite years of begging her mom to bring her along.

She's about to turn 16. That's what I told her, when she was 16 she was allowed to come to a show, Kidman revealed to Vogue Australia in August.

She's wanted to go for a long time.

The following month, Sunday joined Kidman on the red carpet for watch company Omega's Her Time event in Paris.

Although Sunday has been making more public appearances in recent months, her younger sister rarely joins the family on red carpets.

Kidman shares the two girls with husband Keith Urban. The happy couple wed in 2006.

She is also mom to daughter Bella, 31, and son Connor, 29, whom she shares with ex-husband Tom Cruise.
