'Secret Life Of The American Teenager' And 'Baby Daddy' Get ABC Family Pick Ups

ABC Family is becoming the unofficial home of teen parenting programming.

The network has ordered another season of "The Secret Life of the American Teenager," which returns for its fourth season in March. The hour-long drama stars Golden Globe nominee Shailene Woodley ("The Descendants") as Amy, who when we last left her, accepted a proposal from the father of her son, Ricky. No specific details have been announced for Season 5, which will take "Secret Life" past the 100-episode mark.

Continuing with the teen parent trope, ABC Family has also given the greenlight to a new multi-camera, half-hour comedy called "Baby Daddy" with former child star Tahj Mowry and "Dancing With The Stars'" Chelsea Kane. According to a press release from the network, the series was the highest testing comedy pilot in the ABC Family's history. "Baby Daddy" chronicles the life of a young man who suddenly becomes a father when an ex-girlfriend leaves his baby daughter on his doorstep. With the help of his mom, brother and friends, he decides to raise her. Production begins this spring in front of a live studio audience in Los Angeles.

ABC Family will also begin production this spring on "Beverly Hills Nannies," a docuseries following the lives of a group of nannies working in the wealthy 90210 region.

And the network is creating a bit of a family affair, Tahj Mowry's sister Tia has been tapped to star in a new holiday movie, "The Mistle-Tones," alongside Tori Spelling. Production is set to begin in Salt Lake City this month on the made-for-TV film, in which Mowry plays gifted singer Holly who loses a spot in a legendary local Christmas group, founded by her late mother to Marci (Spelling). The injustice prompts Holly to create her own group, The Mistle-Tones, and a holiday sing-off sparks some not-so-friendly competition.
