acmsIf there’s a way that Blake Shelton can be overexposed it may happen tonight as he co- hosts The 48th Annual Academy of Country Music Awards (CBS, 8 p.m.) with Luke Bryan. It will double Shelton’s weekly time on prime time broadcast TV to six hours — nine if you count the three hour rerun of “The Voice” (NBC, 8 p.m.) that runs opposite the awards show from Las Vegas.

The ACMs will also feature performances from Shelton and Bryan as well as Garth Brooks in a duet with George Strait, Little Big Town, Jason Aldean, Eric Church, Kenny Chesney, Tim McGraw, Lady Antebellum, Carrie Underwood, Jewel, Taylor Swift and The Band Perry. Church leads all artists with seven nominations; Hunter Hayes has six, and I’ve never heard of either of them. Swift and Lambert each have five.

The season’s second episode of “Game of Thrones” (HBO, 9 p.m.) pretty much features the characters not included in the premiere last week. It includes some doings of the Stark kids, who are growing older quickly, and the introduction of Diana Rigg, perfectly cast as the grandmother of the scheming Margaery, played by Natalie Dormer — they have the same cheekbones!

Season finales come for all three of Showtime’s current underrated Sunday night series. “Shameless” (Showtime, 9 p.m.), Lip graduates. On “House of Lies” (Showtime, 10 p.m.), Doug and Sarah’s relationship becomes more serious. And on “Californication” (Showtime, 10:30 p.m.), Hank is at another crossroads.

“River Monsters” (Animal Planet, 9 p.m.) returns for its fifth season. They just won’t quit.

Weird Al Yankovic is guest judge as a new season of “Cupcake Wars” (Food 8 p.m.) begins.

Still can’t believe “Mr. Selfridge” on “Masterpiece Classic” (PBS, 9 p.m., check local listings) is an eight part series. It seems like the kind of story that could have been summarized in one or two eposides. Nonetheless, tonight they show how Selfridge was the first to put the perfume counter front and center in department stores.

Death of a newborn is about the worst thing that can happen on “Call the Midwife” (PBS, 8 p.m., check local listings).

“The Real Housewives of Atlanta” (Bravo, 8 p.m.) have a reunion episode and it’s surprisingly cordial. Just kidding, they fight the whole time.

If you thought the “All-Stars” on “Celebrity Apprentice” (NBC, 9 p.m.) was stretching it, how about the cast of “Chopped: All-Stars” (Food Network)? It returns for a new season with Ted Allen hosting.

I don’t find this high-pitched comic funny, but here you go, his latest standup special: “Gabriel Iglesias: Aloha Fluffy” (Comedy Central, 9 p.m.).

A night of one-word suspense titles features two movies by Hitchcock, “Spellbound” (TCM, 8 p.m.) and “Blackmail” (TCM, midnight) as well as the French classic “Diabolique” (TCM, 10 p.m.).

It’s the NCAA Women’s Final Four from New Orleans, with Louisville vs. California (ESPN, 6:30 p.m.) and Connecticut vs. Notre Dame (ESPN, 8:30 p.m.).

Seems odd that “Batman Begins” (ABC Family, 8 p.m.) runs after “Batman Returns” (ABC Family, 6 p.m.).

Johnny Depp double feature! “Edward Scissorhands” (Cinemax, 8:15 p.m.) and “Dark Shadows” (Cinemax, 10 p.m.).

Baseball today includes Yankees at Detroit (TBS, 1 p.m.) and Angels at Texas (ESPN, 8 p.m.).

Hockey action includes St. Louis at Detroit (NBC, 12:30 p.m) and New Jersey at Buffalo (NBC Sports Network, 7:30 p.m.).

NBA games include New York at Oklahoma City (ABC, 1 p.m.) and Lakers at Clippers (ABC, 3:30 p.m.).
