The 39-year-old actor is famed for his dry sense of humour and when the actress turned 29 yesterday (25.08.16), he took to the social media site to pay homage to her as well as Billy Ray Cyrus, who shares the same birthday,

He wrote: "Just want to wish Billy Ray Cyrus the most special, magical birthday ever. I love you with all my heart. Also, Happy Birthday to my wife."

Blake is currently pregnant with the couple's second child and her good friend Taylor Swift also took to Twitter to wish her happy birthday.

She wrote: "HAPPY BIRTHDAY BLAKE! You're a wonderful friend, to humans and koalas alike. I absolutely love you."

Blake recently revealed that her parents, Elaine and Ernie are her nannies, which means she doesn't have to employ a childminder to look after 18-month-old daughter James.

She said: "My parents are pretty much the nannies! They are the best baby nurses you could pray for. They raised five kids so they know what they are doing."

Blake also said she feels extremely fortunate to be a mother, despite being constantly exhausted.

She said: "It's tough when you get pooped on and barfed on, but having a baby is wonderful. Even when it's tough and I'm exhausted I think 'I am so fortunate.' When are looking at your child and she's laughing, it's hard to do anything else."
