Princess Eugenie shares adorable video of baby August on Instagram

Princess Eugenie, who has been sharing several photos (opens in new tab) of her 4-month-old son, August Philip Hawke Brooksbank, on Instagram, posted the little royal's first video on Tuesday. Eugenie released three clips on her Instagram Story in honor of the UN's World Oceans Day.

"Today is World Oceans Day. A day to celebrate our magnificent oceans and all the creatures in them," Eugenie captioned the first clip.

"A day to raise awareness about something so vital to our lives," she wrote in the second clip. And in the caption for the third clip, she wrote, "And a day to cuddle with fluffy sharks." See the cute screenshots below (and listen to the very sweet audio on Eugenie's Instagram Story):

Princess Eugenie is famously close to Prince Harry and Meghan, Duchess of Sussex. That means that second cousin August Philip and newcomer Lilibet Diana Mountbatten Windsor (opens in new tab), who are only four months apart in age, are also likely to share a close bond. (And they are both named after great-grandparents: Lilibet Diana after the Queen and August Philip after Prince Philip.)

After the Sussexes announced Lili's arrival, Eugenie congratulated them with a heartfelt message on her Instagram Story (opens in new tab), as reported by Town & Country. Sharing a stunning pregnancy announcement photo of Meghan and Harry, taken by Meesan Harriman, she wrote, "Congratulations, cousins: ...... I couldn't be happier for you guys," she wrote. Cute.
