How a Poster Changed Everything
Jesse McCartney became a Hacks superfan after watching Season 1 with his wife Katie Peterson. A week later, a friend pointed out something extraordinary. He noticed a Tiger Beat era poster of the pop star hanging on Ava’s bedroom wall. McCartney immediately reached out to Hannah Einbinder via Instagram DM, asking if that was really him. Her response was heartwarming and honest.
Einbinder wrote back saying she’d been a massive McCartney fan growing up and had specifically requested his poster when producers asked what should decorate Ava’s childhood bedroom. This wasn’t just casting magic. It was genuine fandom colliding with television storytelling. McCartney even offered, “If there’s ever a time you want me on the show, let me know.”

Five Seasons Later, Dreams Came True
Five years passed. Hacks moved through four seasons of Emmy-winning storytelling. Then, as the HBO Max series entered its fifth and final season, producers reached out to make the impossible happen. This wasn’t just a cameo. It was a full circle moment for both McCartney and Einbinder.
McCartney confirmed he spent only a couple hours on set, performing “Beautiful Soul” roughly six times with plenty of improvisational moments. He met the entire cast and crew, calling the experience amazing. The pop star praised everyone’s professionalism, though he remained clueless about the scene’s context during filming.
The Emotional Breakdown That Stole the Episode
What nobody expected was just how emotionally overwhelming this moment would be for Einbinder. The actress found herself in tears during nearly every single take. Jean Smart, her co-star, even confirmed that Einbinder was in “hog heaven” watching her childhood celebrity crush perform feet away from her.

“I was sobbing every single take,” Einbinder told major outlets. She wasn’t acting, either. The genuine emotion stemmed from childhood memories and genuine admiration. Growing up, she had McCartney’s posters plastered all over her walls from Tiger Beat magazine. This wasn’t just television magic. It was real nostalgia meeting real fandom.
“It was completely real. I was sobbing every single take. I cried, screamed, threw up when I learned of his cameo.”

Why This Moment Hits Different for Millennials
McCartney’s performance taps into something bigger than just a cameo. Y2K nostalgia is experiencing a cultural moment right now, with Hannah Montana marking its 20th anniversary. Back in 2005, McCartney appeared on The Suite Life of Zack and Cody, performing “Beautiful Soul” during the height of Disney Channel synergy. Today, fans show up to his concerts dressed as characters from those era shows.
What makes this Hacks cameo particularly special is timing. McCartney emphasized that the pre-social media era created something unique. You couldn’t just instantly connect with celebrities online. You had to be there, living through those moments. That immediacy and isolation made the nostalgia even more profound and personal than today’s instant-gratification fandom.
Will This Be the Most Memorable Hacks Cameo Ever?
Season 5 marks the final season of Hacks on HBO Max, with new episodes premiering weekly through the series finale on May 28. This McCartney surprise sets an incredibly high bar for remaining guest appearances. Einbinder called it “one of the best days” of her professional life, and McCartney described it as achieving a childhood dream he never expected to experience.
The real question now is simple. With McCartney nailing this emotional moment and Einbinder delivering genuine tears, is there any other guest star who could possibly top this for pure nostalgic television magic?
