Halloween is meant for tricks and treats, and daytime TV shows are providing plenty of both.

"Today" show co-hosts got their Vegas on with Jenna Bush Hager giving a performance as Celine Dion, and Kristen Welker and Peter Alexander recreating Jennifer Lopez and Ben Affleck's wedding in Sin City. Meanwhile, "The Talk" co-hosts filmed a special episode including Jerry O'Connell as Machine Gun Kelly alongside Natalie Morales as Megan Fox.

The holiday also made a splash Monday with several daytime talk show hosts dressing up in everything from "Black Adam" to Wednesday Addams.

Here are the best looks daytime hosts brought to television for Halloween:

Tamron Hall dresses as Halle Bailey in 'The Little Mermaid'

"Tamron Hall" paid tribute to Halle Bailey, who is set to play Ariel in Disney's 2023 remake of "The Little Mermaid." Dressed in a mermaid costume with red faux locs, resembling Bailey's, Tamron Hall descended on a swing while the backdrop of her show resembled the sea.

Jodi Benson, who voiced the original Ariel in 1989, was a guest for the occasion and gave an impromptu performance of "Part of Your World." Benson also praised her successor, telling Hall, "Halle has just done an amazing job and we are so proud of her and we are so thrilled about this live action movie. We're beside ourselves with excitement."

'Live with Kelly and Ryan' co-hosts wear more than 75 costumes

The annual “Live with Kelly and Ryan” Halloween show is both tricky to pull off and a treat for its hosts.

Kelly Ripa, who began her “Live” tenure in 2001 alongside Regis Philbin and has hosted the syndicated morning talk show with Ryan Seacrest since 2017, says preparation for its annual Halloween show begins Tuesday, just after the previous one airs.

“We plan it all year round, and every year we do a theme around how many costumes we can work into" the event, she says.

This year’s choice  – "Live's Multiverse Halloween: The Best in the Universe" – required more than 75 costumes.

“We are jumping through a portal that will take us as many places as we can go,” says Ripa, 52. “It's like, how many costumes can we torture ourselves with this year? Whereas (in) the early years of ‘Live,’ it was really just us putting on a singular costume and doing the show.”

Monday’s show includes parodies of HBO’s “Game of Thrones” prequel “House of the Dragon,” Netflix’s “Stranger Things,” ABC’s “The Bachelorette,” Hulu’s cooking drama “The Bear” and reality-TV royalty “The Kardashians.”
