FOX's six-episode My Big Fat Obnoxious Fiance series capped off its great ratings run by drawing its big ratings yet during its finale and powering FOX to a win in the Adult 18-49 demographics for the evening.

According to preliminary estimates from Nielsen Media Research, FOX's My Big Fat Obnoxious Fiance finale drew series highs of 21.3 million overall viewers, a 4.2/20 rating/share, and a 10.2/23 in the Adults 18-49 demographic, numbers that ranked it first for the Monday 9 PM ET/PT time period in all three metrics.

Demonstrating that a huge number of viewers didn't want to miss the final big payoff in which Randi Coy and her family discovered that they'd all been duped (the former by FOX, the later by Randi herself), Reuters notes that Fiance's ratings jumped from its first half-hour to its second, rising from 18 million viewers and a 8.8/20 score to 23.8 million viewers and a 11.6/26 score.
