Last week, the pair announced that they were being forced to move from their beach rental home, which they have been living in for approximately nine months. They purchased a new house in September, but delays in renovating, including a major flood, have rendered it uninhabitable for the time being.

On Wednesday night, they revealed that they've moved into the Balboa Bay Resort in Newport Beach, Calif. and will be living there for the next couple of months.
