Miley Cyrus' SNL performance saw ratings drop four per cent compared to last week's show.
The 20-year-old singer doubled as host and musical guest on the US comedy sketch show this weekend, winning mixed reviews from critics.
The outlet reports Miley's show clocked in a 4.5 rating in metered-market households. It also scored a 2.7 in adults 18-49 in the Local People Meters, matching last week's season premiere in that market.
The programme was also delayed 27 minutes on America's East Coast due to a football game, perhaps helping to drive down the number of viewers.
As many expected, Miley raised eyebrows with her return to the popular programme, which included the star "twerking" during an oversexed spoof of US Congresswoman Michele Bachmann.
Miley also addressed her controversial performance at August's MTV Video Music Awards.
"I don't apologise for my VMA performance. If I owe anyone apology, it's the people who make the bottom half of shirts," she mused.
The singer performed her latest single Wrecking Ball and an acoustic version of her dance hit We Can't Stop in between skits.
Miley's new album, Bangerz, is scheduled for release on Tuesday.
