Avoiding the public eye
While the twins never made an official statement, it looks like stepping out of the public eye was a deliberate decision on their part. Despite making numerous media appearances throughout their lives, the two stopped making public appearances of almost any kind after the conclusion of their reality show. Considering that the show ended with the two preparing for their first real job after graduating college, it seems likely they wanted to focus on living normal lives and enjoying a relative amount of privacy.
Speaking of privacy, the twins once had a joint Instagram account where they would post pictures and updates about their daily lives. However, they haven’t updated that account in about seven years. But that doesn’t matter because we now know what the two have been up to recently, and their career is very interesting!
