iHeartRadio Jingle Ball

The roster of talent includes Katy Perry, Meghan Trainor, Jack Harlow, Camila Cabello, the ubiquitous Shaboozey, Gracie Abrams, Twenty One Pilots, SZA, T-Pain, Teddy Swims, Jason Derulo, and many more.

The Secret Lives of Animals

Holiday crowds and related yuletide hubbub getting to you? Nature documentaries offer a great escape, and this 10-part docuseries from the BBC Studios Natural History Unit complies with dazzling images filmed over three years in 24 countries. Revealing a variety of species in their habitats, exhibiting rarely seen behaviors, the series packages its vignettes in themes including “Leaving Home,” “Raising a Family,” “Protecting Yourself,” “Home Making,” “Finding Food,” “The Art of Deception” (watch how caterpillars mimic snakes to avoid predators), “Making Friends,” “Finding a Partner” and “Growing Old.” If you’ve ever yearned to see a reticulated humming frog bond with a tarantula, this is for you.

The Masked Singer

The 12th season of the giddy singing competition kicks off its season finale with the return of Season 5 winner Nick Lachey (Piglet), crooning the holiday favorite “It’s the Most Wonderful Time of the Year.” And then it’s down to business as the final two contestants — the Wasp and the Buffalos trio — perform before the final unveiling reveals who wins the season and who lurks within those elaborate costumes. Followed by the Season 2 finale of The Floor (9/8c).

Bad Sisters

“I can’t deal with any more drama,” gripes the eldest Garvey sister, Eva (series creator Sharon Horgan), as the second season of the Irish dramedy nears its conclusion. Poor Eva — and poor siblings Ursula (Eva Birthistle), Bibi (Sarah Greene), and Becka (Eve Hewson), for that matter — because the shocking twists just keep coming. A betrayal by someone they once considered an ally sets the latest dark comedy of errors in motion, and the last thing these sisters needs is another enemy.
