*Friday’s episode of “20/20” featuring the big reveal of Mariah Carey’s twins was the night’s highest rated program among the coveted “adults 18-49″ group, according to Nielsen.

The broadcast – which featured a Barbara Walters interview with Carey, her husband Nick Cannon and a first look at their twins Monroe and Moroccan – was up a whopping 75% in the demo from last week.

It was helped by a stronger lead-in from “Extreme Makeover: Home Edition,” notes Deadline.com.  The veteran reality series started its Friday debut slow, posting a 1.1/4 in 18-49 at 8 p.m. But its second episode at 9 p.m. (1.7/5) picked up significantly, off only by 2 tenths from the series’ most recent airing on Sunday last week.

Friday’s “20/20” also featured the daughter-in-law of convicted Ponzi schemer Bernie Madoff.
