Julia Stiles is preparing an emotional tribute to her late "10 Things I Hate About You" co-star Heath Ledger for this season's "Dancing With the Stars" Dedication Night, and says rehearsals have already brought her to tears.

Stiles and professional partner Ezra Sosa are set to perform a contemporary routine to "Can't Take My Eyes Off You" — the song Ledger's character famously used to serenade Stiles' character on the high school bleachers in the 1999 film. "It's bringing back so many memories," Stiles told Variety, adding that she's "still, kind of, working it out" but promising the performance "is going to be really special."

Ledger died in January 2008 at age 28. Stiles has spoken only occasionally about their friendship in the years since, making the planned tribute one of her most public reflections on the co-star who helped launch both their careers.
