Kate Hudson shares sweet birthday tribute to fiancé Danny Fujikawa on his 37th ... trends now

Kate Hudson penned a heartfelt birthday tribute to her fiancé Danny Fujikawa, who she first began dating in late 2016, on his 37th birthday.

On Saturday afternoon, the 44-year-old actress gushed about her husband-to-be, who she called 'the most loving, pure, honest, sensitive, brilliant, [and] caring man.'

'Happiest birthday to my love, my partner, my man! I’m so grateful we shacked up together, had a baby and decided to be married…when we have time to plan it,' she captioned a slideshow of pictures and videos throughout their relationship. 

She continued: 'People wonder what makes love last…I wonder too!'  

The mother-of-three, then, urged her more than 17.1 Instagram followers to 'find someone to get weird with.'

While referencing a footage of her and the musician, which showed them goofing around as they made music together, the mother-of-three joked that the video was just 'what happens in our house when there’s day drinking involved.'

The Oscar nominee concluded: 'love you madly @fujikawadanny HAPPY BIRTHDAY.'

Her post included a snap of her partner giving their daughter Rani Rose, three, a kiss on the cheek as well as a family dinner at a sushi restaurant as well as her two youngest children picking up a Christmas tree.

Her comment section was flooded with sweet notes from fans and her celebrity pals, including Chelsea Handler, Leslie Mann and Leslie Odom Jr.

'I love your love, baby!' the 48-year-old Chelsea Lately alum wrote under Hudson's post.

In February, the How to Lose A Guy in 10 Days star admitted that their wedding is still in the planning stages. 

'Right now, planning a wedding feels insane, but I’m excited to plan a wedding, and I go back and forth between a small wedding and a large wedding,' the performer said. 

The Fabletics spokesperson was previously married to the Black Crowes' Chris Robinson, 56 from 2000 to 2007. 

'So there’s a part of me that wants the big bash, you know?' she said. 'There’s, like, two sides to me: the big bash or the small, intimate wedding. I think somewhere in there I’m going to come up with both.'
