Kate Middleton and Prince William are feeling the love on Valentine’s Day!

On Friday, Feb. 14, the Prince and Princess of Wales marked the day in a rare move by posting a photo of themselves sharing a PDA moment on social media.

The photo was captioned with a single red love heart emoji. The image was first released by the royal couple in September 2024 as part of an emotional video announcing that Kate, 43, had completed her chemotherapy treatment following her cancer diagnosis earlier in the year.

The sweet picture shows the pair holding hands as William, 42, kisses Kate on her cheek while she laughs. It appeared to have been captured in a wooded area, with the duo seen sitting on a brown picnic blanket.

The three-minute clip was shot in August by Will Warr in Norfolk, where Kate and William reside in their country home Anmer Hall with their three children: Prince George, 11, Princess Charlotte, 9, and Prince Louis, 6. 

Their more recent public displays of affection are a contrast from years past, when the Prince and Princess of Wales were typically more stoic in their interactions publicly. However, Myka Meier, royal etiquette expert and founder and director of Beaumont Etiquette, previously told PEOPLE, “There is no actual etiquette or royal protocol that says the couple must refrain from PDA.” The likely reason for the couple’s restraint is because they are “working representatives of the British monarchy,” she said.

The prince has remained a constant support for his wife throughout the past year and Kate’s tumultuous time has further strengthened their bond.

A source close to the royal household told PEOPLE last month that the royal couple are “more open” now and “talk about their relationship together.”

“For the princess, family — her husband and­ children — are more important than anything else,” a close royal insider told PEOPLE.
