Bella and Edward may have ended up together in Twilight, but their on-screen portrayers' love story seems more complicated. Kristen Stewart and Robert Pattinson broke up five months ago, but K.Stew was spotted dropping in on R.Pattz on Wednesday, October 30.

A spy tells Us Weekly that Kristen drove into Rob's gated Los Angeles community and spent three hours there — after which the two exes drove out separately, driving in the same direction: toward Kristen's house. When they spotted paparazzi hounding them, they parted ways, Kristen driving home alone.

The two Twilight on-screen/off-screen lovers broke up in May after reuniting in November 2012 (after breaking up in July 2012 over to Kristen's affair with director Rupert Sanders).

But that hasn't stopped the rumor mills from speculating about their seemingly inevitable reunion — and Kristen and Robert may be supplying said mills themselves, if they are indeed hooking up on the down low.

Let's just hope that any canoodling doesn't distract them from their work: Robert is gearing up to film Queen of the Desert, a biopic of archaeologist Gertrude Bell, with Nicole Kidman and Damian Lewis; Kristen, meanwhile, will soon film comedic drama The Big Shoe with Elizabeth Banks and Jim Sturgess.

Do you think Kristen and Robert will get back together? Speculate away below.
