All the tabloid drama over "Speidi," torture chambers and possible lawsuits wasn’t enough to boost ratings for the NBC reality freakshow known as "I’m A Celebrity…Get Me Out of Here!"

Last night’s two-hour edition of "Celebrity" finished a distant third in its 8-10 p.m. timeslot among adults 18-49, dropping 23 percent below the show’s premiere a week earlier. According to fast national preliminary Nielsen data, the ITV Studios-produced series notched a mere 2.0 rating/6 share in the demographic and 5.2 million overall viewers.

The premiere of "IAC…GMOOH!" (pronounced "Ayak-gmooh!") delivered a 2.6 adults 18-49 rating in last week’s preliminary numbers. The show was up, however, from its Wednesday and Thursday episodes last week, which finished in the 1.8-1.9 demo range.

Monday’s "IAC…GMOOH!" focused on the adventures of Heidi and Spencer Pratt, the MTV "stars" known for their "work" on "The Hills."

As for the competition, ABC’s more established unscripted franchise, "The Bachelorette," finished in first from 8-10, averaging a 2.5/7 in the demo and 7.4 million viewers. That’s up nicely from last week.

The intentional comedy of CBS’s sitcom block was a close second in the 8-10 p.m. timeframe, with the network’s four half hours averaging a 2.4/7.

Fox was fourth for the 8-10 block with repeats of "House" and "Bones," averaging a 1.7/5 with its scripted dramas. But "House" actually beat "IAC…GMOOH!" in the 8 p.m. hour, with the NBC reality show starting off the night in fourth place.

In the 10 p.m. hour, "Dateline NBC" and a "CSI: Miami" repeat split the lead with a 2.1/6. ABC’s "Here Come the Newlyweds" was right behind with a 2.0/6.

For the full night, ABC and CBS tied for first in adults 18-49 with a 2.3/7, followed by NBC (2.0/6) and then Fox (1.8/5) .
