Days before her birthday, Kally meets the latest pop icon, who is as successful as he is seductive, but ex-boyfriend Dante still has feelings for her and doesn't want to lose her. While she's having the time of her life, Kally must decide what to do with her career and her heart.
Unfortunately the movie Kally’s Mashup: A Very Kally's Birthday is not yet available on HBO Max.
