President Obama’s address on the nation’s debt ceiling disrupted primetime schedules on Monday, which saw Fox’s ”Hell’s Kitchen” and ABC’s ”The Bachelorette” put up the strongest numbers.

The night’s preliminary, affiliate-based Nielsen results are shaky due to roughly 25 minutes of news coverage consisting of the Obama speech followed by the Republican response at 9 p.m. ET. The lineups for viewers in the western part of the country were not affected.

At ABC, the penultimate episode of this season’s ”The Bachelorette” averaged a 2.3 rating/7 share in adults 18-49 and 7.9 million viewers overall during the 8 o’clock hour, and then concluded following the news coverage with its second hour from 9:30 to 10:30 p.m. (roughly 2.4/6 in 18-49, 7.9 million viewers overall). Finishing off the night was ”Extreme Makeover: Weight Loss Edition” (1.8/5 in 18-49, 5.5 million viewers overall), which ran until nearly 11:30 p.m. in the East.

Fox was strong in Monday’s opening hour with ”Hell’s Kitchen” (2.5/8 in 18-49, 5.8 million viewers overall), which appears to have been the night’s No. 1 program in 18-49. Following the news coverage, a repeat of ”MasterChef” was joined in progress and earned a 1.4/4 in 18-49 and 3.4 million viewers overall during the 9:30 p.m. half hour.

CBS aired repeats of ”How I Met Your Mother” (1.1/4 in 18-49, 4.1 million viewers overall) and ”Mike and Molly” (1.1/3 in 18-49, 4.3 million viewers overall) in the opening hour of primetime, and then followed the Obama address with an encore of ”Two and a Half Men” (1.3/3 in 18-49, 5.2 million viewers overall), a second helping of ”Mike and Molly” (1.1/3 in 18-49, 4.8 million viewers overall) as well as repeat of ”Hawaii Five-0” (1.0/3 in 18-49, 4.4 million viewers overall for its 10:30-11 p.m. portion).

NBC kicked things off with an ”America’s Got Talent” encore (1.3/4 in 18-49, 5.4 million viewers overall), joined ”It’s Worth What?” in progress following the Obama address (roughly 0.7/2 in 18-49, 2.8 million viewers overall in the 9:30 p.m. half hour) and wrapped with a repeat of ”Harry’s Law” (0.7/2 in 18-49, 3.7 million viewers overall).

Preliminary 18-49 averages for the night (including Obama address): ABC, 2.2/6; Fox, 2.1/6; Univision, 1.4/4; CBS, 1.1/3; NBC, 1.0/3; CW, 0.2/1.

In total viewers (including Obama address): ABC, 7.6 million; Fox, 4.8 million; CBS, 4.6 million; NBC, 4.4 million; Univision, 3.7 million.
