The Big Bang Theory actress pulled out all the stops to help her man celebrate his 27th in style, throwing a huge bash at their gorgeous LA mansion.
(FYI, their home is the one previously owned by Khloe Kardashian and seen in the Kardashian reality shows. Jel!)
"I met my husband right after his birthday last year. I finally get to celebrate w him. Oh this is gonna be good....." she told fans.
Kaley, 28, organised an evening party at their home which saw an oversized sign reading 'Happy Birthday Ryan' illuminated over their pool.
She uploaded a video to Instagram showing the moment she surprised Ryan with the birthday. They can be seen standing behind a black curtain in their backyard. The curtain then drops to reveal all Ryan's friends and family crowded into their garden.
Ryan's birthday cake was a pretty amazing looking creation featuring photos documenting Ryan's life from childhood to marriage. The cake was made by LA bakery The Butter End.
Guests ended the night with a midnight pool dance-off, which sounds pretty amazing.
Alongside a photo of herself and Ryan kissing, Kaley wrote: "Happy birthday to my incredible husband ... I can't wait to spend every single birthday with you #lifeisweeting"
She also shared a morning after picture of the pair, looking rather gorgeous for someone who'd been out partying the night before!
Kaley and tennis player Ryan married on New Year's Eve following a whirlwind romance. They met via mutual friends and became engaged three months later, marrying a further three months after that.
