Disney alum Miley Cyrus made fans' crossover dreams come true when she took a selfie with Yani Gellman, aka Paolo from The Lizzie McGuire Movie.

What Dreams Are Made Of

Miley and younger sister and fellow singer, Noah Cyrus, reportedly ran into Gellman while out eating at a restaurant. Overcome with a case of nostalgia, the two women nabbed Gellman for a selfie.

Rather than chastise him for his evil, lip-syncing ways, or for potentially luring Lizzie over to the dark side, Miley and Noah were all smiles in the photo.

"Sing to me Paolo," wrote Noah in the caption, itself a clear reference to the movie.

As fans of a certain age can attest, Paolo meets and falls for Lizzie in Rome in the hit spinoff movie. He, of course, turns out not to be her real Prince Charming — that would be her BFF, Gordo.

Adorably, Gellman seems to have been just as thrilled and starstruck to run into the Cyrus sisters as they were to spot him.

"This is what dreams are made of," he wrote in a retweet of Noah's photo on Twitter.

Gellman's caption is a reference to the most famous song from the movie, the still-irresistible "What Dreams Are Made Of," which Lizzie kills in a live performance after teaming up with her lookalike Italian contemporary, defeating the villainous Paolo.

In fact, the Cyrus sisters even partook in an impromptu rendition of the super-catchy song on Gellman's Instagram story.

Disney Kids For Life

Although Hannah Montana herself, Miley, never appeared on Lizzie McGuire, the two shows were a couple of Disney's all-time greatest hits. In fact, the only thing that could've made this particular reunion even sweeter would have been an appearance by Lizzie (Hilary Duff).

Although she has yet to weigh in on the reunion, Duff spoke positively about Miley's career trajectory in a 2015 interview, praising her commitment to being different.

"I look at someone like Miley, and as crazy as people might think the whole thing is, I commend her. She's so wholeheartedly being herself and is unapologetic about that and she's doing a great job. ... At the end of the day, her talent backs it all up. I don't always relate to everything that she's doing, but I love that she's unapologetically herself," Duff gushed.

The logical next step is for Duff and Cyrus to perform a duet of one of Hannah Montana's greatest songs. Now that would be what dreams are really made of.
