Nicole Kidman and her sister used to speak to each other in a secret language. The Oscar-winning actress is very close to sibling Antonia and says they spoke in a hidden tongue when they were growing up.
Nicole - who is godmother to two of Antonia's four children - said: "We used to have a secret language and all sorts of stuff. No-one will ever come between us. We need that love and support from each other, and we're both willing to give it. She's grown up all her life with a sister who's an actress, and she's been a part of it and held me in her arms when I've cried. She's seen the failures and the successes, and I've seen hers."
When Nicole split from first husband Tom Cruise in February 2001, she took Antonia with her to the premiere of her movie 'The Others' - her first public appearance since their separation was announced - for moral support. The 'Cold Mountain' star, who is now married to musician Keith Urban, insists she and Antonio will always offer each other support, no matter where their lives take them. She added: "We will always be there for each other, no matter what happens." |
