Hillary Clinton’s new book “What Happened” mentioned the name of Kelly Clarkson, including some lyrics from her hit songs, Billboard reported. Aside from her, there were also other musical artists that the former Secretary of State featured in her book.

“What Happened” is Clinton’s first major project after her candidacy in the 2016 presidential elections. It is a memoir of her experiences during the campaign and during her stint of the official presidential nominee of the Democratic Party, Los Angeles Times reported.

The former first lady spent some time quoting some of the lyrics from Clarkson’s song “Stronger.” Clinton wrote, “That which does not kill us makes us stronger – Friedrich Nietzche (and Kelly Clarkson)”

Clarkson and Clinton

Upon reading about that particular line, Kelly Clarkson shared her reaction via her official Twitter account.

The singer tweeted a lot of exclamations, clearly showing that she is overwhelmed with the mention of Hillary Clinton’s book. The tweet included certain emojis showing her happiness.

This singer was discovered from the hit reality singing competition “American Idol.” Since she won that night, she was catapulted to fame with her various awards such as a Grammy trophy for “Stronger.” She is one of the strongest supporters of the former Secretary of State.

Jennifer Lopez, Katy Perry

“What Happened” is a feel-good account of Hillary Clinton’s journey to the United States presidency, as she also mentioned other prominent musical artists of this generation.

These celebrities include Sara Bareilles, Jennifer Lopez, Rachel Platten, Katy Perry and the Roots.

She also made special mention of Andra Day, Marc Anthony, Pharrell Williams, John Legend and Stevie Wonder. Many of these singers have worked closely with the campaign trail, as some of their songs have been used during that time.

The former first lady featured the songs such as “Fight Song” and “Brave” to send her campaign message, Billboard added.

Perry also was among the performers during the Democratic Party’s national convention. The “Roar” singer was very open about her support for Clinton during her candidacy.

‘Saturday Night Live’

Hillary Clinton also did not forget to recognize the touching performance of her impersonator Kate McKinnon on “Saturday Night Live.” McKinnon performed a piano version of the song “Hallelujah” a few moments after the results of the 2016 elections were announced.

She wrote in the book, “As [McKinnon] sang, it seemed like she was fighting back tears. Listening, so was I.” Then, she quoted some part of the song in the new book, Billboard further noted.
