ABC Family has ordered the fifth season of "The Secret Life of the American Teenager". The renewal makes the Shailene Woodley-starring teen drama series the longest-running show in the network's history as well as takes the show into its 100th episode.

In addition to renewing "Secret Life", the cable channel also gave series orders to a multicamera half-hour "Baby Daddy" and a reality series "Beverly Hills Nannies". Both shows will begin production this spring for a summer release.

The former is a comedy featuring Chelsea Kane (previously known as Chelsea Staub) and Tahj Mowry in the cast ensemble, and will follow "a young man who becomes a surprise dad to a baby girl when she's left on his doorstep by an ex-girlfriend." The unscripted program, meanwhile, revolves around "the lives of a group of nannies working for families in the most exclusive zip code in the country."

"We're very proud of our deep bench of original content successfully built out over eight years of exceptional growth," said ABC Family president Michael Riley. "This Summer, we're excited to continue to expand our content across key genres adding another season to our groundbreaking drama, 'Secret Life,' wonderful comedy and a return to reality programming as we continue to innovate with our ABC Family brand."
