The Kardashian family sure move fast: One sister is expecting her first child, another recently got married – and now Kim Kardashian is looking for a house with on-again boyfriend Reggie Bush.
"After they got back together they were both looking for new places and decided to take the next step in their relationship," a source tells PEOPLE.
Kardashian, 29, and Bush, broke up for a while, but reconciled in September.
