"Bachelor" star Jason Mesnick and former contestant Molly Malaney are set to wed Saturday.

But don't expect Melissa Rycroft to be there. (Mesnick, 33, proposed to Rycroft, 26, but then famously dumped her on-air for Malaney, 25.)

Even though Rycroft previously told UsMagazine.com she is "happy" for the two, Us has learned that she will not attend the ceremony, reportedly at the Terranea Resort in Rancho Palos Verdes, Calif.

Expected: Jillian Harris and Ed Swiderski and Trista and Ryan Sutter.

What will the wedding be like?

"We don't want an hour-long ceremony and assigned seating and fancy food," Malaney previously told Us Weekly. "I'd rather have people walk away saying, 'That was the most fun, badass wedding I'd ever been to!"

The wedding will air in a two-hour ABC special, "The Bachelor: Jason and Molly’s Wedding," on March 8.
