Twentythree (alternatively styled "twentythree") is the major label debut album of Californian singer-songwriter Tristan Prettyman. It was released by Virgin Records America on August 2, 2005. It peaked at #24 on Billboard's Top Heatseekers chart. The album was named, at least in part, for the fact that it was released after Prettyman's 23rd birthday. Also, both she and her then-boyfriend, musician Jason Mraz, were born on the 23rd (of May 1982 and June 1977 respectively).
