Kristen Stewart and Robert Pattinson have fuelled speculation they have reconciled following their summer (12) split by stepping out together for a Halloween party in Hollywood on Wednesday (31Oct12).

The Twilight stars parted ways after the actress confessed to a momentary "indiscretion" with her Snow White and the Huntsman director Rupert Sanders.

Stewart publicly apologised to Pattinson when the fling emerged, and last month (Oct12) they were rumoured to have reunited after they were spotted at a Los Angeles bar.

Now the pair has stepped out in L.A. together once again, heading to the Hollywood Forever Cemetery Halloween Party to celebrate the spookiest night of the year, according to JustJared.com.
