Prince Harry's Spare and Britney Spears' The Woman In Me have sold the most print copies of any celebrity memoir so far this year.
According to Circana BookScan data - which tracks point-of-sale data for print copies of books through direct reporting of independent bookstores and major retailers - Spare by Prince Harry has sold 1.19 million print copies since its release on 10 January, reports Forbes.
The Woman In Me by Britney Spears has sold 417,947 print copies - and more than 1 million copies across all formats - since 24 October.
Given Prince Harry's memoir has enjoyed an eight-month head start, Britney's memoir could be on track to surpass Harry's sales by year end.
Additional bestselling memoirs of 2023 tracked by Circana BookScan include Pageboy: a Memoir by Elliot Page (67,038 print copies sold), Love, Pamela: a Memoir of Prose, Poetry, and Truth by Pamela Anderson (58,464 print copies sold), and Paris: the Memoir by Paris Hilton (46,637 print copies sold).
Forbes reports that Barbra Streisand's memoir, My Name Is Barbra - released on 7 November - has been a bestseller since it first became available for presale in February.
Sales numbers are not yet available for Barbra's book, nor for Henry Winkler's Being Henry: The Fonz... and Beyond, which was released on 31 October.
