Prince Louis, the youngest child of the Duke and Duchess of Cambridge, celebrated his first birthday with three new portraits taken by mum Kate Middleton and released via the Royal Family's Instagram page. Following the photo's release, Aunt Meghan and Uncle Harry couldn't help but leave a sweet message in the comments section.
The Sussex Royal Instagram account left a heartfelt comment on Kensington Royal's adorable birthday portraits of the little prince — and the apparent personal touches point to it being written by either Meghan Markle or Prince Harry themselves, instead of the work of a staff member manning the social media pages.
"Happy Birthday Louis!" the comment reads. "Sending lots of love from both of us xo."
The comment comes after speculation Meghan is running the Instagram page herself.
Many fans have also pointed out the fact the note has been signed off "love from the both of us" - seemingly another subtle clue Meghan and Harry haven't welcomed their baby yet.
