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 No. 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). Mraz would later propose to Prettyman on December 23, 2010.
