In this reality-based series, all of whose installments she narrated, singer-actress Lisa Loeb documented her life as a single woman in her mid-thirties as she attempted to re-enter the dating scene after two failed relationships, each of which had lasted six years.
With the help of her sister Debbie (who was also a singer-actress, and single as well), her longtime friend Stephanie, and ex-boyfriend Juan Patino, Lisa was given advice on how to find love.
With her musical career and her pursuit of the perfect man causing a little friction in her life, Lisa hoped that she could balance the two in more ways than one.
The goal Loeb sought was not achieved as a result of Number 1 Single, as the series of events it documented failed to lead to a long-term romance for her.
On January 31, 2009, nearly three years after the series ended, Loeb married Roey Hershkovitz, the music coordinator for Late Night with Conan O'Brien.
