Her father is an American of English and Dutch ancestry and her mother is Korean, originally from Seoul. Frampton often recorded a "song diary," an impromptu recorded song, on her MySpace page. She explained, "It was something very raw, and to be honest, something that I was slightly embarrassed to put up because of the quality but I did anyways, for any of our listeners who would care to hear something not hot off the production belt, but something more organic and 'home made.' It made me feel better to share my feelings with people who could connect, and I think that is what happened with many."[3]

Meg and Dia were originally formed in 2003. Meg, Dia's sister, possesses music ability and the skill of craftsmanship. She creates robot necklaces that are sold on her own blog.
