My love: When Harry and Markle attended a special fundraising performance of the musical "Hamilton" in 2018, the Duchess of Sussex was overheard using the pet name when she turned to make sure she wasn't blocking Harry's view.
Haz: Markle revealed the nickname while FaceTiming with her husband and James Corden during a segment on "The Late Late Show With James Corden" in February 2021. Then in the couple's 2022 Netflix docuseries, "Harry & Meghan," Markle revealed that it was actually one of her friends that gave him that nickname.
