"See Ya" is a song by Atomic Kitten, released as the second single from their debut album Right Now. The single peaked at #6 on the UK Singles Chart, selling 86,773 copies and becoming the group's seventh best selling single in the country. The single also reached #13 in Belgium and #50 in Ireland.
The single was released around the time of B*Witched's final single, Jump Down, and as such, Atomic Kitten were regarded by many as their replacement. "See Ya" was featured in the film Bring It On.
