Prince William and Kate Middleton shared recent clips on their Instagram to showcase the Duke of Cambridge's visit to an emergency services outfit in Belfast. However, some of the followers ended up blasting the royal couple because of their choice of song to go with the video.

The short presentation featured Prince William shaking hands with frontliners and happily greeting a service dog. The clip had Harry Styles' "Watermelon Sugar" as background music, which some royal fans said was a shameless and "saucy" pick.

One follower wrote in the comments that the music wasn't in keeping with the professional image of the Duke and Duchess of Cambridge. Apparently, "Watermelon Sugar" is a sexually suggestive song. 

A commenter asked if William and Kate were aware of the song's implications. According to Pop Buzz, Styles' fans have a theory that "Watermelon Sugar" is about an explicit sexual act.

But more than the mistake in music, one commenter said that changing things up in the royal pair's Instagram was a step in the wrong direction. William and Kate's social media people might have intended to project a lively vibe but the followers didn't like it.

They said that the future King and Queen of England are not social media influencers. Instead of going hip, they said that William and Kate's staff should have posted an informative update about the duke's visit to Belfast. Royal fans advised the Cambridges not to let "teenagers" run their Instagram. 

Meanwhile, despite their faux pas, Kate received a commendation from no less than Queen Elizabeth after the unveiling of her special project. The Duchess of Cambridge finally released the best 100 photos among the 31,000 entries of her Hold Still COVID-19 lockdown exhibit initiative.

According to Entertainment Tonight, Kate presented a small batch of the photos to the Queen ahead of the Hold Still's launch on Sept 14. Her Majesty released a statement to congratulate the final 100 photos. 

The monarch said that she is inspired to see the "resilience of the British people" in the captured images. She also appreciated the "efforts of individuals supporting those in need" as depicted in some of the pictures. 

Kate also debuted a video to highlight some of the best works she picked. She thanked all of the participants who dedicated their time and shared a part of their lives to this fun and inspiring project. Kate also thanked her fellow judges -- National Portrait Gallery director Nicholas Cullinan, Chief Nursing Officer Ruth May, writer and poet Lemn Sissay MBE, and photographer Maryam Wahid.
