Tori Kelly Sings a Muppets Classic With Kermit the Frog Dance Prodigy Maddie Ziegler Makes a Special Guest Appearance

Singing stars Tori Kelly, Jessie J and Kelsea Ballerini lend their voices to some of the most popular and beloved melodies in the Disney songbook when the Disneyland Resort Diamond Celebration is showcased on "The Wonderful World of Disney: Disneyland 60," with Master of Ceremonies Derek Hough, SUNDAY, FEBRUARY 21 (8:00-10:00 p.m. EST), on the ABC Television Network.

Tori Kelly, 2016 Grammy nominee for Best New Artist, pairs with Kermit the Frog for a beautiful acoustic rendition of "The Rainbow Connection" from "The Muppet Movie." Versatile singing artist and Grammy nominee Jessie J will sing the iconic tune "When You Wish Upon a Star" from the classic Disney movie "Pinnochio." Country's rising female artist Kelsea Ballerini will be showcased singing "Part of Your World" from the Disney hit film "Little Mermaid." Young dance phenomenon Maddie Ziegler, known to millions for her appearances on "Dance Moms," will be featured in Ballerini's musical number, with choreography by Travis Wall.

Kelly, who will launch an extensive North American tour in April in support of her Capitol Records' debut album, "Unbreakable Smile," marks her evolution from Internet sensation to "It girl" - a journey which took years of effort to achieve. The re-release of her album on January 29th includes current single "Hollow" and never-before-heard track "Something Beautiful". Her sweet, soaring voice has garnered her over 120 million views on her YouTube channel.

Jessie J's astounding voice makes her a one-of-a-kind singing superstar. The UK-born singer-songwriter released her "Sweet Talker"album in October 2014 to immediate acclaim, debuting Top 10 on the Billboard 200. It featured the blockbuster single "Bang, Bang," with Jessie J teaming with Ariana Grande and Nicki Minaj.

Ballerini launched to stardom with the release of her number one, gold-certified single debut, "Love Me Like You Mean It," and follow-up top ten single "Dibs" - both from her Black River Entertainment debut album, "The First Time," which landed Top Five on the Billboard Country Albums Chart. Proclaimed by Billboard Magazine as "Country's Next Queen," Ballerini received their "Rising Star" award at the prestigious 2015 Women in Music event.

Ziegler became an internet sensation in part, due to her starring in Sia's hit music video trilogy. Additionally, she has performed artistic contemporary dance routines on "Jimmy Kimmel Live," "Dancing with the Stars," "Saturday Night Live" and "The Grammys." She is quickly making a name for herself as an aspiring actress with notable credits, including Freeform's "Pretty Little Liars," "Austin & Ally" and the upcoming feature film "The Book of Henry" opposite Naomi Watts. She also recently took home a People's Choice Award.

Kermit the Frog, the world's most famous amphibian, has been entertaining the planet for more than 60 years. A singer, dancer, bestselling author and the star of many hit movies and TV shows, Kermit currently serves as executive producer of "Up Late with Miss Piggy," as seen in the ABC series "The Muppets."

Walt Disney's legacy lives on through the Disneyland Resort, but even he might not have been able to imagine how big his idea would become at Disneyland and at Disney parks that span the globe. He launched an entirely new concept for family entertainment that remains as relevant today as the day it opened, July 17, 1955, for guests of all ages.

The Disneyland Resort will continue its 60th Anniversary Diamond Celebration through Summer 2016, extending the three spectacular after-dark shows created for the special anniversary - the "Paint the Night" parade, the immersive "Disneyland Forever" fireworks show and the all-new "World of Color-Celebrate! The Wonderful World of Walt Disney." The exciting celebration, which also features sparkling décor, themed food and merchandise, will conclude on Labor Day, Monday, September 5, 2016.
