CBS is showing a little love to "Accidentally on Purpose."

The network has ordered five more episodes of the Jenna Elfman half-hour, insiders confirmed Tuesday. That's short of a full-season pickup but still a modest vote of confidence in the series.

Critics were mixed in their reviews of "AOP," but viewership has been steady. It's been retaining between 80-90 percent of its "How I Met Your Mother" lead-in. Last night, it delivered its best ratings since its premiere (though a CBS affiliate carried Monday Night Football, potentially skewing the preliminary fast nationals).

"AOP" is from CBS Television Studios.

With "AOP" extended, the only CBS newcomer still on the bubble is "Three Rivers." As TheWrap has noted before, however, that series is a dead show walking and, if logic and past history is any guide, it has very little chance of living beyond its initial 13-episode order.
