Disney Channel nostalgia was in full swing this weekend with two different reunions involving stars from Hannah Montana, High School Musical, The Suite Life of Zack and Cody, and Lizzie McGuire.

When Vanessa Hudgens wasn't slaying everyone with her Céline Dion cover or knocking Drake off his feet at the Billboard Music Awards on Sunday (May 21), she was hanging out with Miley Cyrus.

Besides Cyrus, fellow Disney alum Ashley Tisdale — who costarred with Hudgens in both HSM and on Suite Life — attended the BBMAs and had "a loaded question" for Hudgens: "What's your favorite thing we've done together?" Hudgens admitted through giggles that traveling all over the world with her bestie on the HSM press tour and attending Tisdale's wedding were two of the best adventures.

Days before the BBMAs made us feel like it was 2006 again, Lizzie McGuire's Jake Thomas and Hannah Montana's Jason Earles — yes, two more Disney stars — reunited as judges for the UCLA Spring Sing, a showcase highlighting students' talents in "song, dance and sketch comedy."

Earles's fiancée, Katie Drysen, shared a pic of herself with the "Disney bros," captioning, "Disney is kind of like one big family." As it should be.
