"Happy Birthday to my amazing wife. Thank you for joining me on this adventure! — Love, H," he wrote.

While it hasn't been confirmed what Markle gifted her husband for his birthday, for her birthday last month he reportedly gave her a simple but sentimental present.

"The odds are on a sepia or black and white photograph of her precious son in a solid silver frame from Aspreys [a British luxury brand]," a royal source said last month.

"The precious present is likely to have an engraving chosen by Harry that will make it extra special.
