Sydney Sweeney ’s “year of trying new things” led her to skydive just hours after barhopping, the actor told Stephen Colbert on Thursday. (Watch the video below.) Sweeney, who stars in the new movie “Christy” about the boxer Christy Martin, feared her stomach might punch back during her adventure. The “Late Show” host showed a picture of Sweeney in “mid-dive” and learned from his guest that she’s scared of heights and found the experience terrifying. “How do you prepare for that?” Colbert asked.
