Sorry, Betty -- looks like nice girls really do finish last.

Ageless comic book star Archie will end his famous decades-long love triangle in Archie Comics' 600th issue, popping the question to sexpot rich girl Veronica Lodge instead of good girl Betty Cooper, according to the Archie Comics blog.

The cover of "Archie Marries Veronica Part 1: the Proposal" shows redhead Archie Andrews getting down on one knee to Veronica, one of the two swooning girls who've battled for his heart throughout the series' 65-year history of publication.

On the cover, Veronica is seen exclaiming "Yes!" as Archie puts a diamond ring on her finger in a jewelry store, while Betty looks on in tears.

The love showdown between blonde Betty and brunette Veronica has characterized Archie's adventures over the years, as the two fought tooth and nail for Archie's affections.

Archie fans took to the comic book's site in droves to discuss the announcement, which was first leaked May 20 by the New York Post, who reported that Archie would choose one of the women -- but wasn't sure which would be his pick.

The majority of the bloggers wrote that sweetheart Betty should walk down the aisle with their beloved Archie.

"I hope it's Betty! I've read these comics for over 30 years and waited for the day he woke up and chose Betty," said commenter Rachel.

"I think he should marry Betty. Veronica is an air head," fan Shayan wrote on the site.

The issue will be penned by acclaimed superhero movie producer Michael Uslan (Batman Begins) and drawn by legendary Archie Comics artist Stan Goldberg.

It'll also answer questions about the eternal high-schoolers' futures outside of small-town Riverdale High, depicting Veronica, Betty, Archie and best friend Jughead in college, holding down jobs and living adult lives.

Archie Comics issue #600 will hit newsstands September 1, but will be available in comic-book stories July 19 and will be shipped to Archie Comics subscribers July 12.
