Sam and Nicole, 'Beauty and the Geek 4'

Sam and Nicole, 'Beauty and the Geek 4'

Will a Hooters waitress find a kindred soul in a guy who researches quasars? Will a software engineer benefit from his association with a theme park performer?

The nine pairs of "Beauty and the Geek" contestants have one more factor to figure into their social equation on the CW's upcoming fourth season of the hit reality show that will kick off with a two-hour premiere on Tuesday, Sept. 18 at 8 p.m. ET/PT.

Competing against the partnered hot women and brainy men is another incongruous pair: a gorgeous guy and a geeky girl. Sam is a 26-year-old party promoter from Davis, Calif., who will be teamed up with Nicole, a 25-year-old Tufts University musicology grad student from San Francisco. This new couple will not only test the concept of book smarts versus social smarts, but also provide a gender-based twist to the formula.

Among the challenges the geeks will have to meet are performing an autobiographical rap and competing for the title of Prom King. The beauties will be taxed by participating in a debate and substitute teaching a third-grade class.

The winning team will share a $250,000 grand prize.

Last season saw major drama in the form of bikini model Cecille who was the only one who didn't embrace the social experiment aspect of the show, which eventually cost her the win when her own teammate Nate realized her shortcoming and campaigned against his own team. In a way, Nate's integrity was rewarded with an unexpected romance with housemate Jennylee.

Is there another showmance in the offing for this season's contestants? Besides Sam and Nicole, here are the other 18 contenders:
