The Twilight pair – who play Edward Cullen and Bella Swan – broke up after Stewart admitted in July to having a brief fling with her Snow White and the Huntsman director, Rupert Sanders.
After some time apart, Stewart, 22, and Pattinson, 26, met up in Los Angeles over the weekend of Sept. 15 in L.A., and began spending more and more time together.
Now they are officially a couple again. And Pattinson has decided not to sell the L.A. home that he and Stewart shared, according to a source.
