Alexaundra Christine Schneiderman (born December 9, 1996), known professionally as AleXa  and formerly Alex Christine , is an American singer based in South Korea. After competing in both seasons of the reality show Rising Legends, AleXa signed with Zanybros’ ZB Label in 2018 and trained there for roughly two and a half years. During this time, she also competed on Mnet’s Produce 48. She debuted as a K-pop singer in October 2019. In 2022, she represented her home state Oklahoma in NBC’s American Song Contest with the song “Wonderland” where she won with 710 points.

AleXa was born Alexaundra Christine Schneiderman on December 9, 1996, in Tulsa, Oklahoma, to a Russian American father and a South Korean mother. AleXa’s mother was adopted at age five by her adoptive American parents from an orphanage in Goyang, Gyeonggi Province, where she last saw her brother. AleXa has one sibling, a younger brother.

As a child, AleXa took dancing lessons for various genres, including ballet, jazz, hip hop, and tap. She began to dance when she was eighteen months old and continued into mid-high school. She attended Jenks High School where she was a member of the show choirs Jenks Varsity Pom and the Jenks Trojanaires, which competed nationally. She attended Tulsa Community College, where she participated in theatre. AleXa was an avid K-pop fan and created both an Instagram and Snapchat account dedicated to covering K-pop songs and choreography while in school.

In 2016, under the name Alex Christine, she participated in the Rising Legends online audition run by Soompi. The competition was organized in partnership with JYP Entertainment. In 2017, she competed on Rising Legends again when Soompi partnered with Cube Entertainment. Despite placing #1 in the dance category the first time and the overall winner the second,[6] she did not make it into either of the companies’ trainee programs and instead signed with ZB Label as their first (and as of 2022, only) in-house artist.
