Her music career

She used to be a popular teen pop singer in her native England in the late 90's and very early 2000's. She was England's answer to Britney Spears; during Britney's "bubblegum" era. "Day & Night" is pretty much a note-for-note rip-off of Britney's "You Drive Me Crazy" (which was a rip-off of the Backstreet Boys' "Everybody").

Why did she quit recording music after her second album?
