The iconic home is located on Dilling Street in Studio City and served as the exterior for "The Brady Bunch," which aired on ABC from 1969 to 1974.
The asking price was nearly $2 million but no word on what it actually sold for.
Bass tweeted he's super excited to announce his offer was accepted last night.
