Book on 'The Masked Singer' season 11

A new season of Masked Singer means a new slate of celebrities shrouded by elaborate masks and a Twitter feed full of guesses from viewers watching at home. And we're here to help you figure out the famous faces beneath these wilder-than-ever new masks.

The season 11 contestants boast a combined 22 Grammy nominations, 11 platinum albums, 33 Teen Choice nominations, 108 million records sold, 1.7 billion Spotify streams, and 326 film appearances.

The singers may attempt to throw off the crowd, but we'll be watching for tiny clues. Think we can figure out these stars before panelists Ken Jeong, Jenny McCarthy-Wahlberg, Robin Thicke, and Rita Ora?

Let's get started.

Book is ready to take on the new chapter of their storied career with The Masked Singer! The tome is the definition of old school, dressed up as an antique with a bowler, monocle, and mustache to boot. They're accompanied by a bookworm, and hopefully they won't find themselves crawling through the competition.

So the next question is...
