UPN just released information about its two mid-season series, “South Beach” and “Get This Party Started.” The steamy, new primetime drama “South Beach” is being executive-produced by Jennifer Lopez. It centers on best friends Matt and Vincent who abandon their world as they know it and head to the alluring paradise of sandy beaches, beautiful people and hot spots in glamorous South Beach.

Matt's preoccupation with his old girlfriend, fashion model Arielle, has him diving head first into her thrilling new life, even though she has moved on, and Vincent, willing to do anything to get ahead, uncovers the dangerous and seedy underbelly of one of the world's most sizzling locales.

The series stars Vanessa Williams as Elizabeth Bauer, Marcus Coloma as Matt Evans, Chris Johnson as Vincent, Lee Thompson Young as Alex Bauer, Odette Yustman as Arielle Casta and Giancarlo Esposito as Robert Fuentes.

“South Beach” will debut with a two-hour series premiere on Wednesday, Jan. 11. The series will air in its regularly scheduled time period beginning Wednesday, Jan. 18 (8:00-9:00 pm, ET/PT), bridging the current cycle and the upcoming sixth cycle of America’s Next Top Model.

The new reality series “Get This Party Started” will premiere on Tuesday, Jan. 24 (9:00-10:00 pm, ET/PT). UPN will present an encore of the previous week's episode on Tuesdays (8:00-9:00 pm, ET/PT), beginning on Jan. 31.

In “Get This Party Started,” UPN will capture the drama, emotion and excitement each week as an elite team of party planners to the stars, led by special events coordinator Lara Shriftman of Harrison & Shriftman, work with one special individual's friends and family to surprise their well-deserving loved one with a very spectacular and extravagant event in their honor. From the hottest clubs, celebrity guests, and trendiest style-makers all over the country, nothing will be spared to make these dreams come true. Kristin Cavallari (Laguna Beach) and Ethan Erickson ("Extra") host the series.
