The singer/actress and her new actor beau stepped out for a low-key date at a museum on Saturday ... where they got to play with the open-air venue's many interactive pieces, some of which clearly blew Keoghan away.
Check out the pics going around on social media ... it's hard to see Sabrina's expression, but one shot of Barry from the side clearly shows the star's mouth hanging wide open.
As you know, Barry recently revealed in an interview with GQ he'd split with his longtime partner and baby mama Alyson Kierans (who bears a striking resemblance to Sabrina BTW). They're co-parenting one-year-old son Brando.
In any case, Sabrina and Barry make one of the hottest new couples in H'Wood. She's a superstar singer and actress, and he's getting a ton of acclaim for "Saltburn" -- for his performance and his dancing "skills."
