In 2019-2020, Meghan Markle was one of the most intensely-mediated mothers in the Anglophone media. This article examines how UK and US media representations of Meghan negotiate, trouble, challenge, regulate and reassert the boundaries and meanings of contemporary motherhood. Situating Meghan's mediated representations in the context of the increasing visibility and shifting meanings of motherhood in contemporary culture, and particularly in the context of the growing visibility of voices and accounts of "mothering while Black," we examine the mediation of Meghan's maternity in three moments: 1) Prince Harry's announcement of the birth (May 2019); 2) Meghan's public outing with the baby (July 2019), her later (September 2019) interview for an ITV documentary, and lawsuit she filed against the British tabloid Mail on Sunday; and 3) the royal couple's South Africa tour (September 2019). We conclude by examining a fourth mediated moment-"Megxit" (January 2020)-and highlight the mediation of Meghan Markle's maternity as a site that might open up a space for rewriting motherhood, and particularly Black motherhood, however limited that space may be.
