Jason Mesnick a Bachelor No More!

Flip-flopping ABC star marries his runner-up, Molly Malaney, in private reception in Rancho Palos Verdes, Calif.

Do you hear that? It's ABC celebrating—Jason Mesnick didn't change his mind again!

The flip-flopping former Bachelor has married his winner second-banana soulmate Molly Malaney in a made-for-TV ceremony.

The reality romantics swapped vows Saturday as cameras rolled at the the Terranea Resort in the Los Angeles beach suburb of Rancho Palos Verdes.

"This is the happiest day of our lives," the newlyweds said in a statement to OK! magazine.

Former Bachelorettes Trista Sutter and Jillian Harris, along with their respective rose-recipients, Ryan Sutter and Ed Swiderski, witnessed the picture-perfect nuptials. Jason's son, Ty, who played a big role on The Bachelor, was also on hand. Needless to say, Mesnick's first choice and former fiancée, Melissa Rycroft, and new husband Tye Strickland didn't make an appearance.

The bride and her attendants were swathed in Monique Lhuillier, with their hair done by celeb stylist (and Jessica Simpson BFF) Ken Paves, according to OK!, while the groom wore Kenneth Cole.

The couple held their rehearsal dinner Friday night at Terranea's mar'sel restaurant, followed by a prewedding party with friends and family at resort hotspot, Nelson's.

The 33-year-old Mesnick proposed to Rycroft on the 2009 season finale of The Bachelor and then dumped her six weeks later during the reunion special to rekindle the flames with runner-up Malaney, 25. Mesnick popped the question in October in New Zealand, where he'd initially given her the boot.

Bachelor host Chris Harrison recently responded to rumors of tension in the run-up to the big day, telling E! News exclusively: "I've talked to Jason and the only thing he's worried about is putting together a golf tournament for the guys. Seriously, that's the biggest drama! From what I understand, everything's going great."

The happy day will be edited over the coming days and transformed into the special The Bachelor: Jason and Molly's Wedding, airing March 8 on ABC—just one week after current man of the hour, Jake Pavelka, picks his potential copilot.
