The dancer, who shares an eight-month-old son with Tom, posted: "Breaking my social media detox to share this very special moment of 2020.
"As a 'small' fan of Mr @harrystyles it’s an understatement to say that it was a pleasure to be a part of this masterpiece.
"Practising what he preaches & is hands down one of the kindest people I’ve met, teamed with the effortlessly cool & wonderful @phoebewallerbridgeweb - This really is something I will cherish forever."
Singer Tom shared the heartbreaking news about Dani's death on Instagram.

In the announcement Tom, who competed in The X Factor as part of the group Stereo Kicks in 2014, shared a quote Dani had posted on her Instagram account in January 2019.
It read: "Keep the honest moments close to your heart. The ones that are the most human.
"When you laugh until your ribs ache with your friends, when you feel stars exploding inside of you from falling in love, when life breaks you open those tears of transformation pour like a river from your soul.
"Live is really quite simple. We get to experience this planet for a brief while. We get to learn how to love ourselves and one another for the strange, messy, and magical creatures we are."
After hearing the heartbreaking news, X Factor boss Simon Cowell sent his condolences to the singer.
He told TMZ: "As a father myself, I simply cannot imagine the heartbreak Tom and his family are going through and will be personally reaching out to him.
"From my family to his, we extend our deepest condolences and all of our love during this tragic time."
