Jesse Csincsak just got engaged to Ann Lueders.

Now they're expecting their first child together too!

Csincsak announced the happy news in an online video. Lueders, who appeared on the 13th season of The Bachelor featuring Jason Mesnick (who DeAnna Pappas rejected when she got engaged to Jesse) is four months pregnant with a boy.

They plan to name their son Noah.

Congratulations to the parents-to-be!

The soon-to-be-wed parents-to-be are slated to tie the knot in Las Vegas August 28. That would certainly explain the short engagement period ...

Meanwhile, DeAnna Pappas recently announced that she is getting hitched as well - to high school teacher Stephen Stagliano. "I was crying, holding his hands, and he showed me the ring," she said. "I just nodded, like, 'Yeah!'"

Stephen's twin brother was a competitor on The Bachelorette, pursuing Jillian Harris, who Mesnick rejected. Michael Stagliano is also engaged, to Holly Durst, who dated Csincsak after his breakup with DeAnna. Everybody got all that?
