But they waltzed together on Dancing With the Stars and everything!

Jake Pavelka and Vienna Girardi, a match made in ABC heaven just months ago, have ended their engagement, Pavelka's rep confirmed to E! News Monday, bumping the total of failed Bachelor couplings to 13 (if you don't count Jason Mesnick and Melissa Rycroft).

"Jake and Vienna have split and appreciate the respect for their privacy at this time," the rep said in a statement.

Pavelka famously chose Vienna, who was public enemy No. 1 among the Bachelor roommates, over the more grounded Tenley Molzahn, to the consternation of many, prompting the usual cries of "It won't last!"

OK! was first to report this tragic split, which leaves flip-flopper Mesnick as the only Bachelor to lead his chosen one all the way to the altar, say what you will about his breakup to makeup style.

Girardi, 24, told E! News less than a month ago that she and Pavelka, 32, were aiming for a summer wedding next year, preferably on the beach or on an island somewhere.

But a rep for Greek star Gregory Michael confirmed to E! News that Girardi told him at a charity event that she and Pavelka had split up.

For its part in the drama, Warner Bros. Television said about the purported breakup: "As you know, we never comment on rumors and speculation."
