Kristen Stewart's Halloween costume was a tribute to Natalie Portman

KRISTEN STEWART modeled her Halloween costume after NATALIE PORTMAN's stripper character in 2004 romantic drama CLOSER.

The Twilight star was snapped wearing a short pink wig and sunglasses while celebrating the spooky holiday at the Hollywood Forever Cemetery with Robert Pattinson on Wednesday (31Oct12), fueling speculation the couple has reconciled following a summer split (12) due to Stewart's "indiscretion" with married director Rupert Sanders.

And during an interview with MTV.com on Thursday (01Nov12), the actress revealed her outfit was a tribute to Portman: "I love Closer. (It's) one of my favorite movies. If you've seen that, that's one aspect of (Portman's) character. She changes a lot in that movie."

Meanwhile, Pattinson wore a creepy clear mask with bushy eyebrows for the Halloween bash, and the British hunk confesses he picked up the prop at a local convenience store at the last minute.

He joked, "I chose someone who is just genuinely terrifying. It was a $3 mask from a 7-Eleven."
