Portia Reiners replaced Katrina Bowden - before the latter ever shot a scene - in October, 2006. She stepped into the role of Britney Jennings at the time, just as she had on All My Children previously when she took the place of Leven Rambin in 2006, playing the autistic Lily Montgomery.
Portia was named after the character Portia from Shakespeare's The Merchant of Venice.
