Born Althea Janairo in Honolulu to parents of Hawaiian, Chinese, Spanish and Filipino descent, Tia (named by her younger sister who couldn't pronounce her name) grew up dreaming of becoming a singer. Her career in showbiz started at the tender age of 17 when she was discovered in a local grocery store, landing herself the lead part in the movie Aloha Summer.
Tia moved to Los Angeles and, and after a stint on General Hospital was offered a part on Baywatch, which she turned down so she could audition for Wayne's World (1992).
Carrere won the part of rock chick 'Cassandra' opposite Mike Myers, a role that lead to international recognition (and male adoration). Still a passionate singer, Tia provided all of Cassandra's vocals in the movie and soon after released a solo album, Dream, in 1993.
Tia went on to star opposite Arnold Schwarzenegger in True Lies (1994), and more recently in three seasons of the hit TV show Relic Hunter (1999-2002). She recently voiced the part of 'Nani' in Lilo and Stitch, and 'Queen Tyrani' in Duck Dodgers.
Carrere has been named one of People Magazine's 50 Most Beautiful People in the World (1992).
Tia is married to husband Simon Wakelin. She recently gave birth to their first child, Bianca.
