The Australian actress and film producer Nicole Kidman surprised her husband with a cake written in white icing on top saying, "Happy Birthday Big Cat Daddy." Keith Lionel Urban celebrated his 49th birthday last Wednesday, October 26, with the biggest smile because of the surprise of his wife during his day. The Australian country music singer took to Twitter to thank his wife for his blissful birthday celebration.  

He shared two photos on his Twitter account. Urban wrote "Best birthday EVER!!! Love u baby K,". Nicole Kidman and Keith Urban are married since 2006 and have been together for 10 years now.  Nicole has two older children, Isabella Jane Cruise, and Connor Cruise from her previous marriage with Tom Cruise. Nicole has two wonderful children with Keith - Faith Margaret Kidman Urban (5 years old) and Sunday Rose Kidman Urban (8 years old), Just Jared has reported.

Keith said that his wife, Nicole, is unbelievable open and doesn't keep things or let them bottle up. She is a great communicator and because of her, Keith is opening up every day, listening, learning and growing. The singer also added that if he becomes a better man now it's because of his wife. Keith told PEOPLE that they are "pretty goofy" when they're together.

Nicole is Keith Urban's best friend and he never had anybody on this planet that knows him like his wife does. Keith said to his wife: "I'd love to be worthy of somebody like Nic, but I was a long way from it when we met, and somehow we just found there was love, real love. I just literally feel like the luckiest guy."

As a couple, their relationship remained sweet from the beginning until the present year and it might be forever amid divorce rumors coming out as of late.
