The pair, who recently reunited following the 22-year-old actress' "momentary indiscretion" with director Rupert Sanders, are shacked up together and have also adopted a new rescue dog called Bernie, reported Us magazine.
"They are basically living together again," a source told the magazine.
Recent reports suggested that Pattinson is still having a tough time trusting Stewart.
"Kristen is working hard to try and force the relationship into what it was before. But the truth is, she is going to have to take it slowly with Robert because he is still having trouble trusting her again.
"For him to carry on like nothing happened is very hard. Kristen is eternally sorry for cheating on him and he has forgiven her ¿ kind of," the source added.
