Reality bites. Bachelor and Bachelorette alum Tenley Molzahn and Kiptyn Locke have officially pulled the plug on their relationship, a source confirms to Us Weekly.

The pair dated for two-and-a-half years after meeting during the 2010 season of Bachelor Pad, and were both the runners-up on their respective seasons of The Bachelor and The Bachelorette.

Molzahn, 28, won over America during her stint on Jake Pavelka's season of The Bachelor back in 2010, though the pilot ultimately chose to propose to now-ex Vienna Girardi.

San Diego-based Locke, meanwhile, was rejected by Jillian Harris on her season of The Bachelorette after she accepted fellow finalist Ed Swiderski's proposal on the show's finale.

Locke, 35, will next be auctioned off for a date benefitting the Chris4Life Colon Cancer Foundation -- alongside fellow Bachelorette alum Roberto Martinez -- on April 5 in Beverly Hills.

Other past contestants up for bids include this season's finalists Lindsay Yenter, AshLee Frazier, and Lesley Murphy, as well as Ben Flajnick's former fiancee, Courtney Robertson.

Unfortunately for fans hoping to see the Bachelor/Bachelorette alum return to the screen, however, ABC announced earlier this month that Bachelor Pad will not be returning for a fourth season this summer.
