Another awards show cleaned up in the Sunday ratings, and this time the big victor was CBS.

Miranda Lambert, Reba McEntire and Kellie Pickler.

Rhett also took Song of the Year for Die a Happy Man - after a pointed spoof of a snafu at this year's Oscars where La La Land was mistakenly announced as Best Picture instead of Moonlight.

Up for five awards, Lambert, 33, took the stage to perform her new track "Tin Man" before she was awarded the Album of the Year honors. He has since been in a serious relationship with pop star Gwen Stefani of No Doubt, while Lambert is involved with singer Anderson East. But this time, with what I happened to be going through in my life, being honest was never really a choice.

Surely a lot of attention will be given to Florida Georgia Line, who performed at the show with the Backstreet Boys, a moment that would have been hard to fathom during BSB's rise to fame in the mid- to late- '90s. "I'm so thrilled that I can keep pushing forward and making way for other women to do the same thing", said Lambert.

Miranda Lambert's songs frequent the top of charts and include, "Bring Me Down", "Kerosene", "New Strings", "Famous in a Small Town", "Gunpowder & Lead", "Baggage Claim", and "Over You".

The actual ceremony, however, felt decidedly more serious than years past, with a majority of artists opting to perform ballads, and banter from Bryan and Bentley kept to a minimum.

The trio is back from a hiatus with "You Look Good", a soul-infused single that makes good use of horns, and their first live performance of the track doubled down on the brass section.

- Video of the year: "Forever Country", Artists of Then, Now & Forever. The evening kicked off with Jason Aldean performing Lights Come On, which was followed by Florida Georgia Line's H.O.L.Y. and Carrie Underwood singing Church Bells.

Little Big Town won vocal group of the year, beating out Lady Antebellum, which had just performed on the show. The boy band joined FGL for their collaboration, "God, Your Mama and Me", a song that melded the country duo's pop-influenced sound and BSB's multi-vocal attack.

In total viewers, ACM Awards logged 10.9M viewers, sliding just 3% compared to last year's 11.2M, but 32% (aka 5M viewers) compared to '15's 16M.

- New vocal duo or group of the year: Brothers Osborne. She won album of the year for her deeply personal record, "The Weight of These Wings", which she co-wrote in the aftermath of her divorce from Blake Shelton.

- Songwriter of the year: Lori McKenna.
