Wedding planning always comes with its own share of drama, from placating people over the bridesmaids dresses to navigating who does and doesn’t get an invite. For Meghan Markle, she’s also got a pretty difficult estranged family to deal with – her sister’s writing a tell-all book about her, allegedly hopping on a plane to report on the wedding despite not being invited and now her brother Thomas Markle Jr. has penned an open letter to Prince Harry asking him to call off the nuptials.

Her 51 year old half brother shared a handwritten letter exclusively with In Touch, addressed to the royal. Although it was penned under the guise of looking out for him, it becomes clear in just a few lines that it’s a thinly veiled character assassination of his estranged sister.
