But the 27-year-old singer and actress has also found time to write a book, described on its website as "part memoir, part how-to, and part style guide."
Michele showed fans the book cover on Tuesday:
"What do you guys think of my #BrunetteAmbition cover?! I can't wait for you all to read it! #May2014," she also tweeted.
"Lea Michele is one of the hardest working performers in show business and she knows better than anyone that it is difficult to be your best self and keep things in perspective when your to-do list is overflowing and you are faced with challenges," the book's website reads. "A practical and inspirational guide to harnessing tenacity and passion, Brunette Ambition is about living the fullest life, no matter what obstacles life puts in your way."
Brunette Ambition debuts March 13.
