Kate Hudson has marked her first-date anniversary with boyfriend Danny Fujikawa with a touching Instagram post.

The 'Almost Famous' actress has been in a relationship with the musician - who she first met 15 years ago through his step sisters Sara and Erin Foster - for some time following a slow-burning romance, and took to the photo-sharing app on Sunday (03.12.17) to share a picture of the pair kissing on a bridge, whilst Danny was holding his dog on a leash.

The 'Bride Wars' star also revealed how on their first-ever meeting, Danny didn't kiss her, but that their smooch yesterday was ''much sweeter''.

The 38-year-old star - who has sons Ryder, 13, with ex-husband Chris Robinson and Bingham, six, with her Muse rocker ex-fiance Matt Bellamy - captioned the post: ''The first time I met Danny I was 23 and enormously pregnant with Ryder. His step sisters are my best friends @sarafoster @erinfoster and so it goes we have been in the same circle for over a decade!

''A year ago today Danny took me on a hike and what I thought was just a hike with a family friend turned very quickly into an unexpected first date. No moves were made on this first date. In fact, it took months for him to make a first move! And as a kiss on this bridge would have been nice, the kiss a year later was so much sweeter. So on our 15th year of knowing each other we were able to open our hearts to each other to feel so much pure love and it's been truly incredible.! Happy first date anniversary baby. #LoveThisMan #WhatAYear (sic)''

It comes after Kurt Russell, who is in a long-term relationship with Kate's famous Hollywood legend mother Goldie Hawn, revealed he ''approves'' of his step daughter's beau.

The 'Guardians of the Galaxy' actor said recently: ''He's a nice guy, Danny. Yeah, I like him. I always approve. He's a great guy.

''Yeah, he's very special actually ... Kate brings good guys.''
