In honor of boyfriend Danny Fujikawa‘s 33rd birthday, Kate Hudson took to Instagram to celebrate his special day. The How to Lose a Guy in 10 Days star, 40, who welcomed daughter Rani Rose, him last September, shared the sweetest photo of the father-daughter duo alongside one of the most heartfelt messages we’ve ever read.

“This man has given me the most beautiful gifts life can give and the depth of gratitude I feel for the day he was born is beyond any measured spoken word or post,” she gushed in the caption. “I believe that this gratitude exists and is present in our daughter’s joy and her magical spirit.”

Kate even gave a sweet shout-out to Danny’s parents, mom Melissa Linehan and dad Ron Fujikawa. “Thank you Mama Fuj and Papa Fuj for raising this beautiful roller coaster ride of a special human,” the mom of three wrote. “The ups and downs and sideways were all worth it. Happy Birthday baby! @swimswammyslippyslappy I love you.” 

In the post, Danny and 8-month-old Rani can be seen posing for a photo as they relax on a pool floaty. Their adorable bundle of joy had her toes dipped in the water as she is being held by a smiling Danny.

The couple, their daughter and Kate’s other children from previous relationships — 15-year-old Ryder and 7-year-old Bingham — are currently on a luxurious European vacation. On June 9, the blonde beauty shared a stunning snapshot as she cradles Rani in her arms while on a boat in Italy’s Amalfi Coast.

It seems like Kate isn’t the only one who gushes about their relationship. In March, the Lightwave Records founder opened up about loving the Almost Famous actress — who he has been dating since 2017 — while on the red carpet.

“In the face of fear, she doesn’t back down,” Danny told Entertainment Tonight. “I’ve seen her do things that I can’t imagine doing myself and I’m very proud of her. And I’m in awe of her for some of the things that she is able to do when she sets her mind to it.” So sweet!
