AceShowbiz - Hacks has launched its fifth and final season, featuring a special cameo that had been years in the making. This week’s episode, titled “Number One Fan,” included a memorable appearance by singer and actor Jesse McCartney, who performed during Ava Daniels’ birthday party.
Hannah Einbinder’s character, Ava, is the focus of this episode, and the cameo marked a meaningful "full circle moment" for McCartney. He shared that he and his wife became fans of the HBO Max series shortly after it premiered in 2021, which eventually led to his guest spot.
The connection began when a friend reached out to McCartney about a notable detail from the show’s first season finale. He was told to look closely at Ava's bedroom, where a poster of him from his "teen Tiger Beat era" was visible on her childhood wall. This discovery deepened his appreciation of the series and paved the way for his appearance.
McCartney’s involvement highlights the show’s blend of humor and heart, while also emphasizing the impact of the series on both audiences and guest stars. His cameo adds a nostalgic touch for fans familiar with his earlier career, linking past and present entertainment moments within the context of Hacks.
As the final season unfolds, viewers can expect more engaging storylines and notable guest appearances that celebrate the show’s legacy and its unique characters.
