The "Breaking Dawn Part 2" countdown has started, now just 15 days away!

Twi-hards got their daily dose of "Twilight" stars Kristen Stewart, Robert Pattinson, and Taylor Lautner when all three sat down for an interview with MTV News' Josh Horowitz.

There has been a lot of vampire sex talk lately, and the "Twilight" co-stars dished on that sex scenes that fans are waiting to see how it will play out.

Horowitz asked about the vampire-on-vampire sex scene.

Pattinson, 26, responded by saying, "That's a third form of sexuality," with his co-stars laughing with him at the statement.

Oh, I can't wait," Lautner said after Horowitz asked to describe the scene.

Stewart, 22, said, "I'm going to let him take this one," pointing to her real-life boyfriend and fake vampire husband.

Pattinson looked like he wasn't sure what to say, and then he described:

"I haven't seen it yet, so I don't know, but I imagine it's quite like the scene where they're doing pottery in 'Ghost,'" he teased while everyone laughed in response.

The MTV interview seemed very relaxed, something that fans will be happy about.

Stewart and Pattinson also dished on their Halloween costumes. The couple was spotted on Thursday night going to a party.

Horowitz presented them with a photo of them in their weird masks.

"Oh yeah, I look awesome," Stewart said sarcastically about the photo, in which she's wearing a short pink wig and sunglasses and Pattinson is wearing a creepy clear mask with huge eyebrows painted over it. "That's not fair. That's actually a really weird [photo]."

"That's not me!" Pattinson exclaimed with fake outrage, before laughing.

"I love 'Closer.' [It's] one of my favorite movies," Stewart said of the 2004 Mike Nichols-directed movie starring Julia Roberts, Jude Law and Natalie Portman, who dons a pink wig while she's working as a stripper, MTV News explained. "If you've seen that, that's one aspect of [Portman's] character. She changes a lot in that movie, but that's one part, yeah."

Pattinson described the reason for his mask and some other details, "I chose someone who is just genuinely terrifying. It was a $3 mask from a 7-Eleven," he admitted.

The three co-stars presented a "Breaking Dawn Part 2" exclusive clip, where Bella finally finds out why other vampires complained about werewolves: they are definitely smelly. Check out the video below.
