Keith Urban's wife Nicole Kidman got him a birthday cake that had the message ''Happy Birthday Big Cat Daddy'' written on it.

The country music singer turned 49 on Wednesday (26.10.16), and has taken to Twitter to share his gratitude to his actress spouse and their daughters Sunday, eight, and Faith, five, for giving him the ''best birthday ever''.

Alongside a photo of himself and wife Nicole Kidman - whom he married in 2006 - he wrote: ''Best birthday EVER!!! Love u baby xxxxxxx K (sic)''

The tweet also included a picture of his chocolate birthday cake which featured the humorous words in white icing.

The 'Blue Ain't Your Colour' hitmaker then took a moment to thank his ''fans, friends and loved ones'' for all their well wishes on his special day.

He tweeted: ''To ALL the fans, friends & loved ones for gorgeous birthday wishes, prayers, videos, & songs (yep, people actually sang ME happy birthday) ... I say THANK YOU and I love you all. I feel incredibly blessed. - KU (sic)''

The news comes after the 'Wasted Time' singer previously stated that the 'Eyes Wide Shut' actress had made him a ''better man''.

He said: ''Nic is so unbelievably open; she doesn't keep things in or bottle them up. She's really a great communicator. Because of her, if I open up, every day, I'm listening and growing and learning. If I'm a better man, it's because of her.

''She's my best friend. I've never had anybody on the planet that knows me as well as she does. I would love to have been worthy of somebody like Nic, but I was a long way from it when we met. Somehow we just found there was love there, real love. I literally just feel like the luckiest guy on the planet.''
