5. Louis charms the wildlife lovers

PRINCE Louis is one tomorrow — but who’s that posting limelight-grabbing wildlife shots just before the big day?

SUSSEX ROYAL: Nine photos, eight taken by Harry, to mark Earth Day, landed on the Instagram feed hours before William and Kate published new images — taken by Kate — to mark Louis’s first birthday. INSTA-STATS: A moody shot of a rhino lands the Sussexes 771,078 likes and the account has hit 4.9 million followers.

KENSINGTON ROYAL: It’s not Louis’ birthday until tomorrow, but a big day requires preparation and three delightfully gummy pictures of the Prince are a sure-fire crowd-pleaser. INSTA-STATS: Prince Louis lands 1.5 million likes and the account now has 7.7 million followers. WINNER: KENSINGTON ROYAL
