Lea Michele Sarfati (; born August 29, 1986) is an American actress, singer and author. She began her career as a child actress on Broadway, appearing in productions of Les Miserables (1995-1996), Ragtime (1997-1999), Fiddler on the Roof (2004-2005), and Spring Awakening (2006-2008). Michele came to major prominence playing Rachel Berry on the Fox series Glee (2009-2015), for which she received an Emmy Award nomination and two Golden Globe nominations.

On September 18, 2012, it was announced that Michele would be working on her first solo album. She began recordings for the album soon after on October 19, 2012. Michele stated that it was a "pretty slow process" and the album would be more "pop/rock driven" rather than Broadway influenced. On November 27, 2013, it was announced that the first single from her debut album Louder would be "Cannonball", which was released on December 10, 2013. "Cannonball" debuted at number 75 on the Billboard Hot 100, making her the first main Glee cast member to chart as a lead soloist. The single sold over 51,000 copies in its first week of sale. The music video was released on January 9, 2014. Michele subsequently released four promotional singles in the lead-up to the album: "Battlefield", "Louder", "What Is Love?", and "You're Mine". Louder was released on February 28, 2014, and debuted on the Billboard 200 at number four, selling over 62,000 copies in its first week. The second single from the album, "On My Way", was released on May 4, 2014, with the music video premiering on May 19, 2014.  Michele next voiced the lead role of Dorothy Gale in the animated musical film Legends of Oz: Dorothy's Return, which opened in North American theaters on May 9, 2014. In May 2013, it was announced that Michele had signed a deal with Harmony Books and Random House to pen a part memoir, part how-to book titled Brunette Ambition. The book was released on May 20, 2014. Michele had multiple book signings in the United States, including a signing and Q&A event hosted by Jonathan Groff. The book debuted at number nine on the U.S. Nonfiction Best Seller list a week after it was released, and made its debut on The New York Times Best Seller list at number three. Michele released a second book, You First: Journal Your Way to Your Best Life, on September 22, 2015, which was also published by Random House.  In July 2014, it was announced that Michele would guest star in the final season of FX's drama series Sons of Anarchy, playing the role of Gertie, a truck stop waitress who connects with Gemma Teller Morrow (Katey Sagal). Michele's episode, "Smoke 'em If You Got 'em", aired on October 14, 2014. From 2015 to 2016, Michele starred in the Fox horror-comedy series Scream Queens, alongside original scream queen Jamie Lee Curtis, portraying the quirky, neck brace-wearing Hester Ulrich. She was nominated for the People's Choice Award for Favorite Actress in a New TV Series, and two Teen Choice Awards for Choice TV Actress: Comedy and Choice TV: Villain for her performance in the role. On March 15, 2016, the charity single "This Is for My Girls", on which Michele was one of eight featured singers, was released as a charity single. The song, written by Diane Warren, benefited the White House's #62MillionGirls campaign and the Obama administration's Let Girls Learn initiative, set up by the First Lady of the United States Michelle Obama.
