Nicole Kidman, the Oscar winning actress for "The Hours", said her marriage to Tom Cruise wrecked her friendships.

Nicole Kidman said she lost out on the friendships she had kept for years because her former husband Tom Cruise was so private.

Kidman was just 21 when she married Cruise and struggled to keep in touch with her friends because she came from a different world.

In an interview with Glamour magazine she said: "Part of me shut down, put up barriers and became very insular. It was very hard to keep friendships alive during that period."

Since the couple split in 2001, Kidman has rediscovered her childhood friends and she's determined not to let her pals slip away again. She adds, "I've been able to keep my female friendships ongoing, which is so important.

"Recently, I went on a publicity tour and asked one of my oldest girlfriends to come along. Being together was like going back to when to when we were teenagers."
