Joshua Bassett is opening up like never before - not through music but poetry. The 25-year-old actor/singer penned a poetry book called Rookie: My Public, Private and Secret Life, in which he got real about his mental health following his breakup drama with former High School Musical: The Musical: The Series co-star Olivia Rodrigo. In January 2021, the pop star dropped her debut single Drivers License about an ex-boyfriend who moved on with a "blonde girl." Although Olivia didn't name names, many suspected she was singing about Joshua and Sabrina Carpenter.
