Are Dale Levitski and Jack Mackenroth Dating?

According to Bravo's website OutzoneTV.com, Season 4 "Project Runway" contestant Jack Mackenroth and Season 3 "Top Chef" finalist Dale Levitski are dating or, at the very least, have been seen getting up close and personal in public. Levitski, a Chicago native, enjoys cooking and created something he called "flavor math," a process in which he determines the optimal number of spices to put in a dish. Mackenroth, 38, who hails from Seattle, Washington, is swimmer, model and fashion designer.

The Mackenroth/Levitski matchup isn't the first time that reality show contestants have either "cross-pollinated" reality shows or hooked up during the filming of one particular show:

Trista Rehn and Ryan Sutter ("The Bachelorette")

One of the few true success stories to come from this particular reality show franchise, Trista Rehn was a finalist on the first season of "The Bachelor," but her heart was broken and she rode away alone in her limousine. The show's fans embraced Rehn, a physical therapist from St. Louis, and she quickly became the first "Bachelorette" and chose firefighter Ryan Sutter as her true love over several other hopefuls. After a very public wedding that was broadcast on ABC, the two now have a son, Maxwell Alston, who is the first child born to any "Bachelor" or "Bachelorette" alumni.

Amber Brkich and Rob Mariano ("Survivor All-Stars")

This couple looks as if they were destined to meet and fall in love. When selecting memorable former contestants for "Survivor: All-Stars," producer Mark Burnett originally wanted either original "Survivor" cutie Colleen Haskell or "Survivor: The Australian Outback" contestant Elisabeth Filarski (now Hasselbeck), but Haskell declined, as did Hasselbeck when fellow contestant Rodger Bingham couldn't participate. To fill the cute young female quotient, Burnett selected Brkich, who, in all honesty, wasn't that strong of a player.
