“Humor is the cure to everything !!! Play on !!! Volume 2 will be released next year … get ready !!!,” Deadline reports that the since-deleted post read, with Spears claiming her current tome is “the highest-selling celebrity memoir in history.
Is that attention enough to surpass the sales of the current record-holding memoir, Prince Harry’s memoir, Spare? The royal's book sold over 1.43 million copies across all formats on its Jan. 10 release day in the U.S., Canada, and Britain, placing it at the top of the memoir sales game. It's still unknown if the “Toxic” singer managed to topple it, but early sales word was enough that Spears apparently felt invigorated enough to tackle a second effort.
