Robert Pattinson likes his leading ladies "hot," thinks his "Breaking Dawn" love scene with Kristen Stewart is "funny" and looks back at his first "Twilight" red carpet and thinks, "I looked like an old alcoholic."

Yes, we ranged far and wide across the "Twilight" universe on Friday night during "MTV First: Robert Pattinson," a 30-minute live chat with the 24-year-old star. In fact, we hit so many topics of interest to fans of the vampire franchise that we've gathered them all on one page. Consider this a Twi-cheat sheet of everything Pattinson had to say about the series:

On Kristen Stewart
While Rob drew a line of comparison between his "Twilight" co-star and other leading ladies with whom he's shared the screen — "I like being in movies with lots of hot girls," he laughed — he also pointed out how different he is from Stewart.

"I like the kind of cerebral aspect of things, and she has kind of an immediate emotional response to stuff every single time," he said about making various acting choices. "She's like, 'Why can't you understand? It's obvious. You don't know. You shouldn't be an actor!' "

Unsurprisingly, the duo's upcoming "Breaking Dawn" love scene — which we got a peek at in a photo earlier this year — also cropped up during the conversation. "You've got to really know what you're doing. If it's just a sort of arbitrary love scene, it'd be quite difficult," he explained. "The one on 'Breaking Dawn' is pretty funny."

On "Breaking Dawn"
Of all the new talent joining the franchise, 10-year-old Mackenzie Foy, who plays Edward and Bella's daughter, is the one everyone has an eye on. "She's a great actress. She's really sweet," Pattinson told us. "She has to do a hard part as well, because she's doing — I don't want to get into special-effects stuff — but she's playing a baby in some scenes. Oh, man, some of the stuff is so strange. I mean, we've done very strange things on the 'Breaking Dawn' shoot."

Rob also dished a bit about the musical aspects of the upcoming films, shooting down a rumor that he'll sing a lullaby but revealing he will show off some of his musical abilities. "I did play some piano. I'm not sure if that's supposed to be secret," he said. "I was very impressed. I hadn't played piano in years, and I learned it in about 10 seconds."

On Revisiting the Past
While we had Rob live and in studio, we couldn't help but flash back to our first-ever "Twilight" interview back in the spring of 2008. Though much time has passed, Pattinson said that now, much like then, he still can't quite grasp the full breadth of Twi-mania. What has changed, he added, is how he acts during interviews.

"I never got that I was supposed to be talking about 'Twilight.' I thought I had to be funny all the time and that's it," he said.

But he doesn't regret trying to be the always-on funnyman. Looking back on the last few years, Pattinson told us he really has just one regret. "I wouldn't have worn the suit I wore for the first 'Twilight' premiere. It was too small," he said. "I was also a little bit nervous, so I had a couple of drinks beforehand. I look like an old alcoholic."
