Blue Ivy Carter is an American singer. She is the first-born daughter of musicians Jay-Z and Beyoncé. Two days after her birth, Time dubbed Carter "the most famous baby in the world." That same day, her breathing, cries and coos were featured on the song "Glory", by her father Jay-Z, which earned her a Guinness World Record for being the youngest person to have a charted song on any Billboard chart. She has been the subject of depictions in media, including impersonations on Saturday Night Live and RuPaul's Drag Race.

"Glory" is a song by American rapper Jay-Z featuring his daughter Blue Ivy Carter and background vocals from Pharrell Williams. Produced by The Neptunes, it premiered on Jay-Z's official website LifeandTimes.com on January 9, 2012, two days after his wife Beyoncé gave birth to the couple's first child Blue. "Glory" debuted on US urban contemporary radio stations on January 17, 2012. The melodic hip hop track is an emotional homage to Jay-Z's then-newborn child and wife. Lyrically, "Glory" is about the experience and happiness of becoming a father for the first time, while also detailing the heartbreak the couple suffered over a previous miscarriage. The song opens with Blue's first heartbeat, and includes a sample of Blue's cries towards the end. The song also contains samples from "The Most Beautifullest Thing in This World", written and performed by rapper Keith Murray.
