“Kelly behind the scenes is the same way you see her on camera. She is hilarious. She’s really real and caring. I’ve always looked up to her and now that I can get advice from her, it’s incredible,” Cartelli said.

“I’m gonna be Brynn’s big sis for life. One just because I love her parents. We would totally barbeque. She’s kind of stuck with me regardless if she desires it or not,” Clarkson joked. “I love being her friend, I love being her mentor and being her cheerleader.”

Establishing herself as a growing musician in her hometown through school talent shows, Cartelli enjoyed playing at local coffee shops and smaller venues before finding success onThe Voice.

Cartelli auditioned not one, buttwotimes — once in New York and then in L.A. — before taking the stage in front of the judges and getting a four-chair turn from during the blind auditions. She picked Clarkson because she said she has always been a fan of the “Piece By Piece” singer.

“[Kelly has been] setting me up for a future after the show so that everyone has an idea of who I am as an artist so that the fans who followed me on this journey get what they deserve from me, which is a pop/soul style of music,” Cartelli previously told reporters about what kind of coach Clarkson is, having been down this singing competition path, herself, when she won the first season ofAmerican Idolin 2002.

“She’s so encouraging and down to earth,” Cartelli — who just released her first single “Walk My Way” — said.
