“Challengers” stars Zendaya, Josh O’Connor and Mike Faist sat down with “Extra’s” Terri Seymour to dish on their steamy drama about a love triangle between tennis pros. Zendaya and Josh also shed light on the weeks of training that went into learning tennis and being nervous they wouldn’t be good. The trio also opened up about their much talked-about threesome scene and how “embarrassing” sex scenes can be, noting what the audience doesn’t see behind the camera. Plus, Zendaya spoke about her press tour fashions and creating a character – and yes, she does chill out in slippers at home! “Challengers” is in theaters April 26.
