Describing her fiancé Ryan Sweeting as “wonderful,” Parsons, 40, joked that he plans on taking full advantage of the fact that the 26-year-old is a tennis player.
“I’m a big, big tennis fan and he’s a tennis player, so I expect to exploit this relationship for all it’s worth for tickets to events,” Parsons told PEOPLE at the GLSEN Respect Awards in Beverly Hills on Friday. “I want Serena Williams’s autograph!”
Parsons’ costar, Mayim Bialik, also shared her excitement over the 27-year-old Cuoco’s engagement.
“I have all the best wishes that I can offer for her,” Bialik, 37, said at the event. “The cast spends more time with each other than anyone else that we know, so we want all the best for her. She seems super happy, and he seems super happy.”
As for why Cuoco and Sweeting make a good couple, for Bialik the answer is simple: “They’re both extremely attractive!”
