Sydney Sweeney isn't letting the backlash from her American Eagle ad get her down. "Sydney thinks this whole thing has been blown out of proportion," a source exclusively tells Us Weekly. "She's focusing her energy on work, including being back on set with her Euphoria family." (Production on the long-awaited third season of the HBO show, in which Sweeney plays popular high schooler Cassie Howard, began earlier this year.) Us Weekly has reached out to Sweeney's rep for comment.
