Alex and Addison originally auditioned for the roles of Phoebe & Steffy on The Bold and the Beautiful against Jordan Mella & Chandler Mella who went on to book the roles. Jordan & Chandler spent only a few three weeks as Phoebe & Steffy before it was announced that the role would be recast. Alex & Addison auditioned this time against Kylie Tyndall & Keaton Tyndall who went on to book and hold the role for over a year. When it was decided that Phoebe & Steffy were to again be aged, Alex & Addison finally got their chance and were contracted to the roles. They were dropped from contract to recurring after only six months and eleven episodes on the show.
Addison is the identical twin sister of Alex Hoover.
