The Secret Life of the American Teenager by Michael Ansell/ABC Family The Secret Life of the American Teenager by Michael Ansell/ABC Family

It's a milestone! The Secret Life of an American Teenager's midseason finale on Tuesday night delivered 4.5 million total viewers, setting a series high in that measure, as well as in the 18-49 demo. The closer represents ABC Family's most-watched original series telecast ever.

Naming names (if not talking utter smack), the cabler also notes that the finale's audience - as well as its performance in several key demos - was better than that of any episode of the super-trendy Gossip Girl. And versus Tuesday's 90210, Teenager performed better in the women 18-34 and 12-34 categories by double- and triple-digit percentages.

The Secret Life of the American Teenager returns in January with 12 new episodes. - Matt Mitovich
