Fans are fired up after Disney Channel left Demi Lovato and Hilary Duff out of a social media post celebrating the network's 40th anniversary.

Shared April 1, the video features several of the channel's biggest stars, including Selena Gomez, Jonas Brothers and Zendaya, doing their signature "Wand ID" bumpers, where they draw a Mickey Mouse logo.

Watch below:

Notably, Duff — the channel's earliest breakout icon and success story, as well as star of Lizzie McGuire and Cadet Kelly — and Lovato — another of the channel's biggest stars, who rose to fame alongside Gomez in the late 2000s and early 2010s with Sonny With a Chance and Camp Rock — aren't featured in the compilation.

After the video was shared, fans expressed their outrage on social media, with many slamming Disney for omitting two of the channel's most prominent and influential stars.

"Hey, she’s DEMI LOVATO and will forever be a disney channel icon!" one fan tweeted

"Disney had no right to snub demi lovato like that," someone else wrote

"The Hilary Duff erasure!" another person shared.

"You forgot the first one, the original one, the icon... HILARY DUFF," another tweeted.
