Nicole Kidman still suffers stage fright.
The 54-year-old actress starred in 'The Blue Room' on Broadway in the 90s and in 'Photograph 51' in London's West End in 2015, but Nicole admits that her stage fright has become even more "intense" over recent years.
She said: "I almost had a heart attack doing that play. The stage fright gets more intense as you get old. Everyone said it would get less scary. It did not."
The Oscar-winning star - who Sunday, 13, and Faith, 10, with Keith Urban, as well as Isabella, 29, and Connor, 26, with her ex-husband Tom Cruise - prefers to spend time in Nashville, Tennessee, with her young daughters than put herself through the stress of a live performance.
She told DuJour magazine: "I have this huge desire to be there for them. I don’t want to miss their bedtimes. That bedtime is so deeply important for me. We talk. We try to have some consistency.
"The biggest consistency is ‘I’m here and I love you and that will never change.’ It’s a constant balance."
Meanwhile, Nicole recently insisted she hasn't got the voice to star in a Broadway musical.
The acclaimed actress is one of the most sought-after talents in Hollywood, but Nicole would feel "insecure" singing on Broadway.
Asked about the possibility, she replied: "I don't think my voice is strong enough. It's not strong enough. I mean, Broadway is like … and also I just would feel so insecure."
Nicole is a huge fan of musicals - but she doesn't feel ready to perform in one.
She said: "I want to go and watch Broadway. I love going to see Broadway. I can't wait to see Hugh Jackman. 'The Music Man', here we come!
"But yeah, no. I don't feel strong enough or secure enough to sing on Broadway."
