The pair starred together in the play Betrayal on Broadway in 2019, and they made their red carpet debut as a couple at the Tony Awards back in September. The play starred Hiddleston as Robert, a man whose wife Emma (played by Ashton) is having an affair with his best friend, Jerry. The story follows the infidelity in reverse, from its aftermath to its beginnings. A source close to the production told PEOPLE in March that the mostly private couple always had "lovely" chemistry together. Yui Mok/PA Images/Getty "They were very private publicly, but behind the scenes you could just see a lovely chemistry," the insider recalled. "There were twinkles in both of their eyes, and the entire company, including Charlie Cox, were all very close." "And being Brits abroad, they would hang out frequently. Zawe and Tom showed great affection for each other, and you could also see that coming off slightly in their onstage performance," said the source. The insider added, "Tom has always been a very, very private person. Behind the scenes, they would just privately be affectionate and hugging and sitting next to each other and holding hands."
