It's been three years since "Breaking Dawn - Part 2" closed the book on "The Twilight Saga" -- at least, until those mini-movies pumped some new blood into the series -- but at Tuesday (Aug. 18) night's premiere of "American Ultra," Kristen Stewart got some bloody good support from her old wolfpack pal Taylor Lautner.

Yes.

Taylor came out to support Kristen's new action-comedy for its Los Angeles red carpet roll-out, which is the first time the two have walked a carpet together since 2012.

Judging by the pics, they're still as chummy as ever because they fell right into that comfy lean routine they'd mastered so well during their time playing Bella and Jacob in the epic five-film romance series.

We're definitely feeling this low-cut floral mini-romper on the oh-so-leggy KStew, and Tay looks all grown up (tears!) with his well-groomed facial hair and perfectly tailored sport coat.

Most importantly, though, they look like they were having a blast together again, which makes us do the flaily dance so hard we might have to call in Dr. Cullen for some medical assistance soon.

So. Stinkin'. Sweet.

And although we were pretty surprised to see Tay make an appearance at Stewart's movie opening, we probably shouldn't have been because this is kind of a regular thing for these two.

Remember when he came along for the ride at her and Dakota Fanning's "The Runaways" premiere in 2010?

And then they both showed up for "New Moon" director Chris Weitz's "A Better Life" prem in 2011, too.

Looks like Kristen Stewart and Taylor Lautner are taking that "Twilight" tagline of "Forever" straight to heart, and we are eternally grateful for their undying devotion to one another.
