In 2000, she attempted to become the United Kingdom's entry into the Eurovision Song Contest, with two songs shortlisted. Her composition "The Answer" was eliminated in a radio semi-final, but "Crazy" was selected for the TV heats. She failed to win the bid, losing out to Nicki French, who went on to finish 16th at the Eurovision final.
Throughout this period, Porter wrote songs having landed a deal with Jive Records. However, after the release of one single and album, Porter parted ways with Jive. After relocating back to New York, getting married and becoming a mother, she recorded an album of standards with James Pearson, released as Gems for Ruby on the Swing Cafe label. One of the tracks is a cover of Queen's "Somebody to Love", featuring Brian May, which was released as a single.
On December 13, 2010, she joined the cast of the Broadway production of Next to Normal as the stand-in for the role of Diana.
